Democratic 'Development': Amiga 
Programming in the New Age 

By Louis R. Wallace 18 

With the graphics-oriented, icon-based 
approaches found in AmigaVision and 
other authoring-system packages, pro- 
gramming the .Amiga isn't jusl for "pro- 
grammers" anymore. Lou Wallace takes 
you on a tour of where Amiga program- 
ming has been — and where it's likely to 
go in the future. . .

CHIEF CONCERNS 

Matters of the moment: ADA aweigh, piracy, 
and viral infection. 



"We should have made an 

example of this jerk, 

and put him in 

the slammer." 



USUALLY THIS COLUMN spends 12 
or so consecutive paragraphs discussing 
one topic. Many subjects are worth the 
effort, and some people even read these 
columns to the end. Other topics are im- 
portant, but deserve far less space. So 
this month we'll introduce a new style 
and talk about a lot of different things 
with no particular connection except that 
they somehow relate to the Amiga. 

ADA on its way: As you probably know, 
the Amiga Developers' Association has 
officially been formed. Although it 
sounds like a real organization (board of 
directors, name, legal status, etc.), it is 
still an infant. Like any youngster, it 
needs nurturing and, perhaps, even a 
little discipline. But mainly it needs par- 
ticipation, ideas, and effort. 

Here's the skinny: ADA Chairman 
Mike Haivorson of Impulse is currently 
in the midst of an aggressive member- 
ship drive, and is also putting together 
an extensive position paper on Amiga 
technology^ that will be distributed to the 
computer and mainstream press. The 
timing couldn't be better. Journalists 
now perk their ears at the mention of 
the Amiga, and the old Commodore im- 
age is slowly but inexorably fading. 

If you've got any bright ideas for 
Mike, and the will to back them up, I'd 
suggest you drop him a line or give him 
a call at Impulse in Minneapolis. 

Another swell idea: A few months ago, 
I called upon AW readers to write to 
particular publications that heavily influ- 
ence PC buying. So far, it has worked. 
I've heard from people at those publica- 
tions who are now a bit more curious 
about the Amiga. And I've seen some 
great letters published. Let's keep it up. 
Heads are turning. Why not twist them a 
little more, eh? 



Copyprotection and piracy: In the PC 
market, copy protection is obscene. 
There is a huge market of responsible 
business people willing to shell out S495 
for a word processor. If you can't make 
it in the market, it's your fault. 

Unfortunately, our market is different. 
Is is smaller. Prices are lower. And soft- 
ware vendors need revenues to develop 
new products and upgrade older ones. 
Software piracy hurts these firms, and 
then ultimately hurts users as software 
dries up. The problem is that all forms 
of copy protection so far devised not 
only intrude upon the honest user, but 
also are not effective in preventing in- 
genious pirates from making copies. 

We need a compromise that serves both 
users and vendors. Maybe the ADA could 
help both parties decide on a uniform 
standard— at least for now. Later, when 
we have an installed Amiga base equal to 
IBM's, we can get rid of all the protection. 
Write us and let us know what protection, 
if any, you'd be willing to accept and we'll 
pass it along to the ADA. 

No mercy: The probation given to 
Robert Morris has got me hotter than an 
Eskimo at Spring Break. As you may re- 
call, this joker gooped up thousands of 
computers with his sneaky, slimy virus, 
and then got famous for it. So we give 
this yahoo probation? We should have 
made an example of this jerk, and put 
him in the slammer. Viruses are an inva- 
sion of privacy, destroy property (infor- 
mation is property), impair your ability 
to work, and weaken the market for 
shareware and PD software. Let's put 
low-lifes like Morris in jail— not on the 
front pages of computer magazines. ■

REPARTEE 

Comments, complaints, and concerns 
from Amiga World readers. 



Kudos for 
Commodore 

IN RESPONSE TO the letter 
from Brian G. Wilson (Apr., p. 
8), I'd like to relate my experi- 
ences with Commodore. Last 
summer I wrote a letter to 
CBM president Harold Cop- 
perman, voicing concerns over 
the future of the Amiga. A few 
weeks later, 1 was surprised to 
receive a reply from Mr. Cop- 
perman in which lie gave me a 
rundown of his plans to im- 
prove the Amiga's market posi- 
tion in coming months. About 
the same lime, I wrote to 
Amiga Product Manager Keith 
Masavage telling him what I 
would like to see Commodore 
produce in the way of Amiga 
products. A month later I got a 
personal and informative letter 
from him as well. 

I believe that the Commo- 
dore of old is gone, replaced 
by a dedicated and aggressive 
team determined to push the 
Amiga hack into the limelight. 
The company still has a long 
way to go in terms of cus- 
tomer support, but has made 
astounding strides over the 
last year. I have the greatest 
faith in Commodore's new 
management. 

Jeff James 
Roy, UT 

IN RECENT ISSUES, I have 
read a lot of complaints about 
Commodore and its advertis- 
ing strategies. I agree with 
most of the criticisms and see 
that many are constructive, 



but let's have a little more pos- 
itive reinforcement out there. 
Commodore is at least trying] 
I'll do my part right here by- 
saying "Thanks" to Commo- 
dore for its effort in promot- 
ing the Amiga. 

Mike Manzatto 
Stuttgart, W. Germany 

On the Chip List 

WITH ITS 32-BIT bus- 
something that should have 
been available long ago — the 
A3000 looks great. As a 
professional, though, I need 
more colors and real ray-trac- 
ing. These are things that 
should have been incorpo- 
rated into the A3000. 1 can't 
wait another year for Commo- 
dore to come out with a 
graphics board. If the only 
way to add belter graphics 
and more colors is to make 
changes to the hardware that 
will render it incompatible 
with some software, so be it. 
This is a price we can pay for 
progress— look at the Macin- 
tosh line. Better software will 
be written. More and more of 
kite, I find myself using other 
computers to get the effects I 
desire. I hope this situation 
changes; I do enjoy working 
with my Amiga. 

Steven R. Collins

EVERYWHERE YOU LOOK 

on the A3000, you can see that 
Commodore focused on high- 
speed throughput. Unfortu- 
nately, however, vestiges of the 



16-bit era remain: The Paula, 
Agnus, and Denise chips are 
not just accessories, but the 
cornerstones of ihe machine. 
In 1984, these chips were state 
of the art, but chip design and 
manufacturing has advanced 
significantly since then. A com- 
pletely new 32-bit chip set is 
essential to Commodore's fu- 
ture in the professional PC 
market. 

I suggest adding 32-bit data 
paths throughout, a 28.56 
MHz clock, 8192 24-bit color 
registers, and four 16-bit 
channels for CD-quality stereo 
sound. If CBM can't produce 
these, it should ally itself with 
a mainstream chip manufac- 
turer. The importance of such 
a set is so obvious that Com- 
modore must be working on it. 
If not, my kids will continue 
playing games on the A500 
while 1 am stuck for life using 
Intel-based PCs at work. 

Mark Shackelford 
The Colony, TX 

ALTHOUGH THE A3000 is a 
significant improvement over 
other Amiga models in terms 
of throughput, its lack of im- 
proved custom chips is disap- 
pointing and makes for a 
bottleneck in the system. 
Amiga owners have long been 
crying out for more resolution 
and colors. If all Commodore 
can do is suggest we buy up- 
grade cards, then all I have to 
say is "Sayonara." Newer sys- 
tems with superior graphics 
and sound will begin emerg- 
ing soon— some may even im- 



plement multitasking. Are you 
listening, Commodore?

Now and Then 

READING YOUR FEATURE 
on the new A3000 ("Welcome 
to a New Generation!," Jun. 
'90, p. 19) took me back to 
when 1 bought my first A1000. 
After four years ol self-train- 
ing, writing proposals, and 
much persuasion, I convinced 
the administration of Laramie 
County Community College to 
add computer graphics 
courses to our curriculum. 
Lasi fall, I started my first 
classes with an A 1000, five 
A2000s, and two printers. This 
spring, we offered six graphics 
courses using an A2500, 10 
A2000s, and four printers. 

These classes fill up almost 
immediately each semester, 
and we plan to add courses in 
advertising and other design 
disciplines. More Amigas are 
arriving, too: The LCCC library 
computer lab will add six 
A2000HDs and an inkjet 
printer for the fall '90 semester. 
Ours is the only curriculum 
and lab like ii in Wyoming and 
possibly in the region.

New Student or Teacher? 



DANTE, ERASMUS, AND COPERNICUS once trod the ancient 
halls of the University of Bologna, Italy- Now the Amiga has gained 
admittance, thanks to the repeated recommendation of Dr. Raffaele 
Cocchi, tenured researcher of foreign languages and literature in 
the English and American Department. 

For three years, Dr. Cocchi waged a three-pronged campaign: 
to get Amigas into the University, to convince Commodore to 
improve the Amiga narrator so it will speak European languages 
with the proper rhythm and accent, and to develop Amiga software 
useful to studies of language and literature. 

He claims victory on two fronts. The University of Bologna now 
has five .Amiga computers, one donated by Commodore Italia for 
Cocchi's research. With the assistance of Vanio Preti, a senior 
student of statistics and a skilled programmer, Cocchi created three 



highly useful programs in both Italian and English. Uiterary .Amiga 
is an extensive program for analyzing literature and poetry that 
produces detailed, neatly printed concordances and statistical ta- 
bles of various word patterns, frequencies, and locations. Polyglotti 
speaks text in Five languages with greatly improved speech quality 
and shows the text transcribed in IRA. (International Phonetic 
Alphabet). The Right Editor is a text editor that writes from right 
or left and includes fonts for Hebrew, .Arabic, Russian, and IPA. 
To help other scholars, Dr. Cocchi is negotiating with Risorse Per 
La Didattica to distribute the software in Europe. 

For more information on Dr. Cocchi's projects, you can contact 
him at DIPA Lingue e Lett. Strani, Strada Maggiore, 45, 40125

high-end Macs and IBM holding out 
on Its rumored low-cost machine, 
Commodore has an opportunity to

The art of telecommunications. 



Introducing two new state of the art 
modems. Applied Engineering's DataLink 
2000™ and DataLink Express™, the most 
feature-packed 2400 baud modems available 
for the Amiga. Bring home a world of informa- 
tionirom up to the minute flight information 
to whole libraries of resource materials. 
Access countless bulletin board services. 
Even download free software and games. 

For Amiga 2000s, 2900s and 3000s, 

the DataLink 2000 (above, at right) is the 
internal board that plugs directly into one 
of the computer's internal expansion slots. 

For ALL Amigas, the DataLink Express 
external modem (above, at left) plugs into 
the computer's serial port. DataLink Express 
features a twelve lamp status light array 
and AE's exclusive "Line Engaged" indicator 
to show a shared phone line is in use. 

Send- fax is an inexpensive upgrade option 
for both DataLink modems. Actually fax 
text and graphics at 4800 baud directly 
from your Amiga screen — without ever 
having to print a hard copy of the infor- 
mation. Program Send-fax to send any 
number of documents, at any time, to any 



fax machine. MNP-5 is another upgrade 
option that compresses data to increase 
transmission speeds up to 4800 baud, while 
automatically correcting errors. 

We include free communications soft- 
ware on disk with every DataLink modem. 
So there's nothing more to buy. The soft- 
ware package includes file transfer capa- 
bility, text capturing and phone directory. 
And both DataLink modems are fully com- 
patible with Bell 103 and 212 protocols, as 
well as European protocol CCITT V.22 BIS, 
V22 and V.21. They operate at varying trans- 
mission speeds from 300, 1200 to 2400 baud. 

Both modems carry five year warran- 
ties, are fully Hayes AT compatible, com- 
patible with A-Talk III, Baud Bandit and 
virtually all other Amiga communications 
software and have FCC certified designs. 
Both come complete with non-volatile mem- 
ory, two modular phone jacks for data and 
voice calls, an on-board speaker and an extra- 
long cable, just in case your computer is 
across the room from your phone jack. 

Lots of freebies. We also throw in a nice 
collection of goodies — a free subscription 



to the GEnie network worth $29.95, S60 worth 
of free on-line time from NewsNet, a free 
$50 subscription to Official Airline Guide, a 
$20 discount package from Delphi and more.

UltraDesign 

Three-part harmony 
By Ron Bissett 

ULTRADESIGN, THE LONG-awaited, 
computer-aided design (CAD) system 
from Progressive Peripherals, impressed 
me from the start with its logical design. 
Its features are on a par with other 
professional-level CAD software, and the 
dual-disk program is well documented in 
a 348-page manual, which begins with 
an easy-to-understand explanation of ob- 
ject-oriented graphics and the basics of 
UltraDesign. 

The program's hard-drive installation 
program is wonderfully simple and 
works perfectly. You just create a direc- 
tory on any partition and double click 
on the HDInstall icon. In a few mo- 
ments, you are ready to go. You can 
move the default locations for the var- 
ious support files by changing the 
UltraDesign. config text file. 

In the main UltraDesign window, you 
will find icons for the three program 
modules: UltraDesign, CADverter, and 
PasteUp. Through the UltraDesign mod- 
ule, you can create, edit, organize and 
set up drawings for output. Importing 
files, saving drawings in IFF format, and 
even creating hatch files takes place in 
CADverter, while plotting is done from 
the PasteUp module. 

Input Here 

When you enter the UltraDesign mod- 
ule, a title screen appears, telling you 
that you are about to put "Thought into 
action. . .At the Speed of Light" (always 
a secret desire of mine). Just select the 
Draw option from the pull-down menu 
and then choose Lines, Circles/Ellipses, 



Text, Dimensioning, or Hatching/Filling. 
Selecting any of these items summons to 
the far left of the screen a set of icons 
associated with that drawing mode. The 
ability to position drawing entries pre- 
cisely is essential, and UltraDesign's 
placemen! options— Endpoint, Midpoint, 
Perpendicular, Center, Intersection, and 
Stored Points— are the minimum accept- 
able for professional use. 

The program's lack of menus to select 
digitizing pads is an omission that should 






YOUR TURM 



With a turbo board and extra RAM, 
UltraDesign runs very well, but on a 
stock 1-meg Amiga, it is far too slow. 
UltraDesign has many good features, 
including a great interface, printer util- 
ity, and file-interchange program. It 
lacks other features, however; I find 
myself using X-CAD Professional to 
draw, and then using UltraDesign to 
print. 

Chad Kielkopf 
Sturgis, MI 



be corrected, even though there is provi- 
sion for efficient production by using 
both menus and keyboard commands. 

When using menus, you cannot enter 
x and y coordinates from the keyboard. 
You can perform most mouse functions, 
however, by making keyboard entries 
after activating a Shell-like dialog win- 
dow. The only way to use the dialog win- 
dow r and the graphic interface 
simultaneously is either to enter one 
dialog command at a lime or several to- 
gether in a script (text file) using the 
menu command Take. But, while this is 
powerful, it is not a completely smooth 
process. 



The Launch command starts an 
ARexx procedure which is then executed 
in UltraDesign. The sample Dialog/ 
ARexx script supplied with the program 
is an indication of this feature's power. 
Programming ARexx routines requires 
such extensive effort that most individu- 
als will not use this feature, but the 
promise of third-party customized appli- 
cations gives it great potential. 

Other powerful features are the dy- 
namic Zoom and Scroll options. With 
these, you can zoom into one section of 
the drawing to identify a point, then 
zoom out, pan the screen (using the bars 
on the bottom and right sides), and 
zoom back in to digitize another point. 
The range of the zoom is almost infinite. 
You control zooming by the pull-down 
menus or keyboard, and you can easily 
program zoomed views into keys 1-9 on 
the numeric kevpad. 

Hard Currency 

Creating an object in UltraDesign in- 
volves first sketching it on screen in the 
default green color. At this point, your 
object is not part of the drawing file, so 
you can alter it. To make the entry part 
of the file, click on the quill-and-bottle 
icon. The object will begin to flash red. 
This blinking, which can be annnoying 
but cannot be turned off, indicates the 
"current" object. Using the Cursor-right 
and -left keys, you ran move backward 
and forward through the drawing list to 
select another object and make it 
current. 

Another way to reassign "current" sta- 
tus is to highlight Edit Current Object 
on the menu and Find Object on the 
submenu, and then select another object 
in the drawing. Only one entry can be 
current at a time, and you can return 
the current entry to the sketch state by 
clicking the eraser icon. This is a novel 



12 August 1990 



approach to object selection. I appreciate 
its keyboard alternate, as repeated trips 
to the pull-down menus make object se- 
lection somewhat slow and clumsy- 
Only the current object can be directly 
added or removed from the Clip buffer. 
To manipulate noncurrent objects, you 
must place them in the Clip buffer by 
highlighting Clip Clipping Box on the 
menu and then choosing one of three 
different object-selection methods from a 
submenu. 

This arrangement involves an extra 
step not required by other programs; 
when erasing several small, connected 
objects, you must zoom and pan many 
times to identify things. The Find Object 
function is of little help here, because it 
can identify only one object at a time. 
The developer needs to insert a method 
for finding several objects at once with- 
out using windows. 

Lined Up 

The program defaults to drawing lines, 
and the Draw Lines icon list at the left of 
the screen has several great features. 
One of the most impressive is the Multi- 
ple Line Mode icon. It draws any num- 
ber of lines, evenly spaced at any 
distance you specify, parallel to a line 
you draw. A nice surprise, and a boon 
for architects, is the fact that when you 
draw a zigzag in this mode, the program 
automatically trims any overlap where 
the parallel lines turn and intersect. 
Other line options are arrows, boxes, 
polygons, lines parallel, perpendicular or 
at other angles to a given line, as well as 
horizontal or vertical lines. Be careful 
with the last two: The system crashed 
whenever I tried to force a vertical line 
in Horizontal mode. 

The Draw Ellipse command brings up 
the Circle/Ellipse icon menu, and you 
can determine placement by setting the

centerpoint, radius, and starting and 
ending angles. After you sketch an el- 
lipse and before you render it, you can 
rotate it around its centerpoint from the 
icon menu. When I tried to use the Edit 
Razor command to break a circle into 
two arcs, nothing happened. A call to 
customer support revealed that ellipses 
and circles do not support this com- 
mand, but that programmers are busy 
correcting this shortcoming, 

UltraDesign doesn't skimp on fonts; 
there are 18 styles available, and you can 
create your own as well. The program 
also supports auto-dimensioning for ver- 
tical, horizontal, or angular distances be- 
tween two points. There is no provision 
for measuring or dimensioning angles or 
arcs, but otherwise the dimensioning 
function has all the necessary features, 
including the placement of dimensioning 
text and the units of measurement to be 



used. UltraDesign does not automatically 
update dimension measurements when 
you change an object's size. 

One of my favorite UltraDesign fea- 
tures is the Draw Hatching/Tilling op- 
tion, which provides 40 patterns that 
you can output to a pen plotter. To fill a 
polygon with a hatch pattern, simply 
draw the polygon and click inside it— the 
hatch fills in automatically. Sadly, pat- 
terns are incredibly slow to render, a fact 
that becomes increasingly irritating every 
time you redraw. On the positive side, 
this gave me lots of time to read the 
manual and discover that the program- 
mers mercifully provided an option to 
substitute a quick, simple color fill for 
the hatch.

Once you get used to the tools, they

Design format. You can also create DXF 
files from UltraDesign files by using the 
Save DXF Interchange selection and 
supplying the proper pathnames. 

UltraDesign can also read IntroG^D 
(Progressive), Aegis Draw (Oxxi), Hew- 
lett-Packard Graphics Language (HPGL), 
and Roland DXY files, and can save 
drawings in IFF format. I wish it could 
also write in Aegis, Sculpt, and other 
Amiga formats. 

On the Outs 

The PasteUp program is another depar- 
ture from the usual CAD output rou- 
tines. It lets you load any number of 
drawings and place, scale, or rotate them 
individually, using either the keyboard 
for exact positioning with x and y coor- 
dinates, or the graphic interface. 

The Setup option lets you choose from 
many output-device drivers, including 
Hewlett-Packard, Houston Instruments, 
Roland, and PostScript plotter drivers. 
The Houston Instruments device driver 
did not list our DMP-61 plotter, but by 



calling customer support, I found that 
all I needed to do was alter the X Inch/ 
Step using the Change Setup feature to 
make it work. 

In outputting a drawing containing 
some hatching, I noticed that the plotter 
handled the main body of the drawing as 
fast as the PasteUp program sent the 
data. (The program sends each line to 
the plotter as it renders it on screen.) 
When it reached the hatching, however, 
the plotter ground almost to a halt. I 
could find no Abort command, and 
turning off the plotter had no effect on 
the PasteUp program. Resigned to my 
fate, I timed the task. This 3 X 5-inch 
hatched area took over two hours to 
plot! My frustration prompted me to in- 
vest in a 68030 accelerator, with which I 
was able to test UltraDesign's coproces- 
sor version. Everything speeded up, but 
hatching was still too slow. 

UltraDesign is a good piece of soft- 
ware, and you can put it to work almost 
instantly by using the pull-down menus. 
You can quicken your pace using key- 
board equivalents, but you will probably 
only approach the Speed of Light— not 
equal it. The Dialog and ARexx features 
allow versatility and open many possibili- 
ties for UltraDesign. The program's ma- 
jor drawback is its inability to output 
UltraDesign drawings to other Amiga 
graphic programs for 3-D manipulation, 
desktop publishing, or video production.

AUTOSCRIPT 

Draw on the count of 3-D 
By Mitch Wells 

I SUSPECT THAT many Amiga artists 
who are comfortable with two-dimen- 
sional paint-and-draw programs are ap- 
prehensive about three-dimensional 
rendering programs. Although they 
would like to integrate 3-D objects into 
their work, they are intimidated by the 



prospect of creating them from scratch. 
AutoScript by Computerall Services is 
not the onlv Amiga program capable of 
converting 2-D artwork into 3-D pieces. 
But while other conversion utilities inter- 
face with paint programs, AutoScript 
converts PostScript output from draw- 
programs such as Gold Disk's Profes- 
sional Draw (so far the only such pro- 
gram for the Amiga, although others are 




Converted EPS lite filled with DlgiWorks, ren- 
dered In Sculpt 4D. 

promised), and also from three pro- 
grams for the Macintosh and MS-DOS 
platforms, (To use Mac and MS-DOS 
output, you must convert it to Amiga 
format with a platform-transfer utility.) 
AutoScript can output to two modeling 
packages— Sculpi-Animate 4D (Byte by 
Byte) and Turbo Silver (Impulse)— and, 
with the help of Syndesis' Interchange, 
to other formats as well. It also directly 
supports the IFF-to-3-D converter, Digi- 
Works (Access Software). 

With the abundance of paint programs 
on the market and the established soft- 
ware for getting IFF output into three 
dimensions, why would you want to 
bother converting PostScript files? One 
reason is that draw programs provide 
tools that facilitate quick logo design. 
Also, because draw programs define ob- 
jects mathematically, they produce ultra- 
smooth images that retain integrity when 
resized. 

Images produced in paint programs, 
on the other hand, are defined in terms 
of bitmaps, and when bitmapped images 
are enlarged, their jagged edges are ex- 
aggerated. Finally, while working with 
draw software can be more time con- 
suming (screen refreshes take longer), it 
can be easier and more precise. (You

can, incidentally, import bitmap images 
into draw software, and trace them to 
produce PostScript objects.) 

Fill Me In 

Using AutoScript is simple. Through 
pull-down menus, select an output for- 
mat (Sculpt, Silver, or DigiWorks) for 
your object, give it a file name, and load 
the PostScript file. AutoScript draws an 
outline on the screen as it creates the 
3-D object. (Although most draw pro- 
grams give you control over color and 
shading, AutoScript converts only out- 
lines.) It then saves the outline to disk. 
You can load this outline into your 3-D 
program, but before you can render it, 
you must fill it in with polygons. 

The easiest way of accomplishing the 
fill process is either to use Sculpt-Ani- 
mate's automatic-fill function (Turbo Sil- 
ver offers no such convenience) or to 
save the outline as a DigiWorks snapshot. 
I strongly recommend using DigiWorks. 
It is much faster; in fact, AutoScript pro- 
vides support for DigiWorks precisely 
because of its ability to quickly fill objects 
with polygons. A single letter T in the 
Palatino font, made with Professional 
Draw and converted with AutoScript, 
took hours to fill in Sculpt-Animate 4D, 
but less than two minutes in DigiWorks. 

You can take your filled outline into 
the third dimension either by extruding 
it to give it depth, or by spinning it on 
an axis to create an object whose surface 
is defined by the 2-D line. Because it 
works from outlines, AutoScript does not 
handle complex objects well— creating a 
3-D automobile would be difficult, for in- 
stance—but 3-D logos and objects for fly- 
bys are incredibly fast and easy to pro- 
duce with AutoScript. 

AutoScript can also work backward, 
converting wireframe Silver and Sculpt 
scenes (you determine the angle and size 
of the view while in the 3-D program) 
into two-dimensional clip art. The 2-D 
output is not in PostScript format, how- 
ever, but in Encapsulated PostScript 
(EPS) form. 

EPS does not show : up on screen when 
imported into your desktop-publishing 
program; the only way that you can see 
an EPS file is to output it to a PostScript 
printer. (AEPS— Amiga Encapsulated 
PostScript— which tags EPS files with an 
IFF representation of the EPS image, is 
not widely used. Until this format is im- 



plemented, desktop-publishing programs 
will probably not display EPS files on 
screen.) 

Finicky for Formats 

There are a few drawbacks to AutoScript 
and the whole conversion process, and, 
thankfully, the manual clearly points 
these out. AutoScript does not like com- 
plex Pro Draw files, and is specific about 
the size of the PostScript files it handles, 



especially when converting to DigiWorks 
format. A tree that I created in Pro 
Draw and filled using DigiWorks, for in- 
stance, came through AutoScript dis- 
torted. Also, while AutoScript provides 
four conversion resolutions for Post- 
Script files, 1 experienced unpredictable 
results when outputing Pro Draw images 
in anything but the lowest setting. Points 
that came through properly connected 
in the Course setting were unconnected >■

The Serial Solution 

25 + 9= expandability 

By Sheldon Leemon 

KNOWING THAT CHECKPOINT 
Technologies calls its dual-serial card for 
the Amiga 2000 or 3000 The Serial Solu- 
tion, you might find yourself wondering 
what the problem is. After all, doesn't 
the Amiga ahead)' have a serial port? 

Well, part of the problem is that one 
serial port is sometimes not enough. Be- 
cause the serial port is the only two-way 
communications port the Amiga shares 
with IBM-style computers, PC serial pe- 
ripherals are the easiest to adapt to the 
Amiga. As a result, there are a dispro- 
portionate number of peripherals that 
use the Amiga's serial port: input devices 
like audio digitizers, optical scanners, 
touch tablets, touch screens, and wireless 
mice; output mechanisms like printers, 
plotters, and film recorders; and control 
interfaces for MIDI devices, video re- 
corders, and video-disc players. 

While a serial switch box lets you plug 



in multiple devices at the same time, it 
does not let you use them simulta- 
neously—something you need to do in 
order to take lull advantage of the Ami- 
ga's multitasking capabilities. A multime- 
dia author, for example, may want to 
use a laser-disc player and a touch 
screen at the same time. 

The other part of the problem is that 
the -Amiga's standard serial port is fairly 
slow and has no input buffer. This 
makes it difficult to obtain reliable trans- 
fers at speeds as low as 9,600 bit per sec- 
ond (bps), particularly when using a 16- 
color hi-res screen. The Serial Solution 
solves this dilemma by providing a 
4-byte hardware buffer for each port, so 
as to make the board suitable for use 
with high-speed modems and high-speed 
serial networking. 

The Long and Short of It 

Checkpoint's Serial Solution is a full-slot 
plug-in card. Unlike other tnultiserial 
cards, it provides one full-size, 25-pin 
D-shell connector. (There is not enough 
room on the mounting bracket for two 
full-size connectors.) This connector- 
unit 0— is almost identical to the stand- 
ard serial port; It even supplies power 
on the same pins as the Amiga's port. 
That's important, because it means that 
MIDI adapters for the Amiga 2000 work 
with the Serial Solution without 
modification. 

The other serial port— unit 1— uses a 
9-pin D-shell connector that is config- 
ured to use the same cable as the serial 
port on IBM AT-type computers. You 
can program both ports on the board to 
any of the speeds (up to 125,000 bps) 
used by the Amiga port, including the 
oddball MIDI speed. In fact, the Serial 
Solution board goes to the extraordinary 
length of including a separate oscillator 
to produce the exact 31,250 bps speed 
required by MIDI devices. 

It should be noted, however, [bat ac- 
cording to the manual, you can set only 
one non-standard rate (above 38,400 
bps) at a time. This means that both 
ports cannot be set to different high- 
speed rates simultaneously, although 
both can use the same high-speed rate. 

The Serial Solution includes both Exec 
and DOS-level software support. The 
Exec device driver, ckptss. device, is simi- 
lar to the standard Amiga serial. device, 
and you install it by dragging its icon 



into the Expansion drawer. The main 
difference between this device driver and 
the standard one is that it supports unit 
numbers higher than (0 and 1 if you 
have one board installed; higher num- 
bers if you have more boards). The 
Exec-level driver is used directly by pro- 
grams that access the serial port. 

Some terminal programs— such as On- 
line! Platinum (Micro-Systems Software), 
A-Talk III (Oxxi), Baud Bandit (Mich- 
Tron), and the shareware program 
JRComm— support serial drivers other 
than serial. device and can use either of 
the Serial Solution ports without modifi- 
cation. Checkpoint covers programs that 
do not directly support alternate serial 
devices by providing a couple of meth- 
ods for accessing their Exec-level driver. 
The first involves "patching" these pro- 
grams—automatically replacing the text 
string "serial. device" with the string 
"ckptss. device"— using a program called 
ZapPort. 

If you do not wish to alter your pro- 
gram files on disk, you can use the sup- 
plied NewPort utility, which creates a 
small (under 1 K) launcher program to 
load the terminal software, replace the 
text string in memory, and then execute 
the program applications. This approach 
has the advantage of letting you operate 
either through the default serial port or 
through unit of the Serial Solution 
without taking up as much disk space as 
two full program versions. 

Whether you use NewPort or ZapPort, 
you should be aware that the unit num- 
ber of the serial port does not change. 
Programs that do not let you select a 
unit number, then, work only with the 
25-pin port— a significant drawback. 

AmigaDOS software support is pro- 
vided by a handler, tss-Handler, which 
corresponds to the DOS SER: handler. It 
enables you to mount the SER2: and 
SP.R3: devices, which you can use to per- 
form any normal AmigaDOS operation, 
such as copying a file or printing to one 
of the serial ports. You can specify de- 
fault communications settings for these 
DOS-level devices by adding a Tool 
Types entry in the icon for the serial 
driver. The Serial Solution does not in- 
clude a handler for unbuffered serial I/O 
like the AmigaDOS AUX: device. This 
means that you cannot use its serial 
ports to open up a remote CLI console

emember those first com- 
puters? Mammoth, room- 
sized colonies of glowing 
i vacuum tubes, they needed 
the continuous ministra- 
tions of entire cults of 
white-clad techno-priests 
working in perfectly sterile conditions to keep them 
running. Programming them was an exercise best 
left to your neighborhood nuclear physicist, as it 
involved such actual hardware modifications as re- 
moving a wire, carefully threading it through the 
machine, and plugging it in somewhere else— just to 
change a byte. Making a modest alteration in the 
program code meant calling a staff meeting; replacing 
the operating system (such as it was) required an Act 
of God. 

Of course, it got better with time. Programming 
with wires wasn't any fun, so some potential Nobel 
Laureate invented the dip switch— a revolutionary 
development because it also involved a hexadecimal 
keyboard that allowed you to enter numbers directly 
into the machine. All you had to do was flip some 
dip switches to define an address and then carefully 
type in the value for that byte. It didn't take too long 
before the dip switches themselves were replaced by 
the numeric keyboard— allowing you to enter both 



the address and the value in relatively easy fashion. 
At this point the nuclear-physicist type lost his cushy 
job because now everything could be done by the 
white-clad techno-priests in their clean rooms. 

Further evolution spawned such remarkable user 
developments as paper tape, punched cards, and 
alpha-numeric keyboards. Soon video terminals be- 
gan appearing, the techno-priests were laid off, and 
a new professional appeared on the scene— the Pro- 
grammer. Highly trained, this exalted being was able 
to say such things as "Opcode" or "Fortran" in mean- 
ingful ways during a conversation and, if provoked, 
to unleash a diatribe involving such arcane topics as 
object dumps of core memory. A breed apart, this 
individual ivould bequeath us such magnificently ob- 
scure legacies as Cobol; he would serve as the un- 
pleasant stereotype of the computer programmer for 
an entire generation. 

The advent of the microcomputer changed com- 
puter programming dramatically— in two ways. With 
inexpensive desktop systems readily available, the 
ordinary engineer or physical scientist could now 
enjoy easy access to a computer— and the opportunity 
to program with it. This spurred a rich, accelerated 
growth in the development of more powerful, so- 
phisticated, and flexible computer languages. Besides 
the low-level assembly language, there was now a

'Development' 

The fact is that programming isn't just for "programmers" anymore. The approaches 

embodied in .such Amiga software as multimedia-authoring systems and other 

application-generating packages represent a brand-new way of thinking about 

programming. Just as the user interfaces of today's computers reflect a revolution 

in making computers more accessible to a larger public, so too have current 

development techniques made programming more intuitive, easier to write, 

and open to wider participation by ordinary computer users. 
AmigaWorld's Senior Editor of Technology Lou Wallace takes a broad look at 
current Amiga programming trends and how they evolved from earlier, more 
traditional approaches to program design and implementation. 



diverse collection of high-level languages thai in- 
cluded Fortran, Cobol, BASIC, Rascal, Modula II, 
Forth, Ada, Lisp, Prolog, Logo, and C— all with im- 
plementations on the ubiquitous personal computer. 

A New Orientation: OOP 

Today my Amiga computer, with its many megabytes 
of RAM, hard disk, high-speed 68030 processor, and 
graphical user interface, bears little resemblance to 
the computer dinosaurs of the past. And like the 
hardware itself, the methods by which we create pro- 
grams have continued to evolve. While some of this 
progress originated in the world of modern main- 
frame systems, the most interesting aspects are orig- 
inal developments for desktop computers. Al- 
though almost every major existing program- 
ming language is currently available on the 
Amiga, the development of new approaches 
to program creation continues— and the 
results will undoubtedly be appearing on 
the Amiga for some time to come. 

For example, with Lattice's C+ + 
package, Amiga C programmers can uti- 
lize the many Object-Oriented Program- 
ming (OOP) design and implementation 
techniques. OOP (and Object-Oriented Design, 
OOD) is concerned primarily with the manipulation 



of "Objects" (collec- 
tions of data) and 
the design and 
function of 
"Classes" 
(the tem- 
plates 
that

SPEAK 



define the objects). It involves a different philosophy 
from that of "Top-Down" programming techniques. 
where the programmer defines the sequence in which 
the program ilow will occur and then builds [he code 
accordingly. With OOP. the programmer first fully 
defines the problem the program must handle. He 
or she then defines the objects (data) to be manipu- 
lated and the class (template) best suited to handle 
the data structures. Once objects and class have been 
defined, the programmer must determine what op- 
erations (verbs) will be performed on or by the objects. 
Object-oriented programming holds a great deal 
of promise, especially in development situations 
where each module is created and compiled sepa- 
rately. Although some may welcome its intuitive ap- 
proach to programming, OOP is not necessarily for 
everyone. Even many experienced programmers find 
it too rigid and complex for their own use. The fact 
remains that for many people, the logic and structure 
of most programming languages continue to be too 
complex and uncomfortable. For the average com- 
pute]* user, even these relatively newer approaches 
seem just as difficult to understand as the techniques 
used by the mainframe programmers and technicians 
of a generation or two ago. 

Design Your Own Application 

All this, however, appears to be changing, just as the 
computers themselves are becoming easier to use, so 
too are the means of creating programs. Just a few 
years ago, commercial programs began turning up 
that allowed even nonprograminers to create cus- 
tomized database .software. To create your own ap- 
plication, you merely answered a series of questions 
that defined the custom application. The code-writing 
part of the program then did a lot of writing to the 
disk, which eventually produced a very large pro- 
gram, usually in BASIC, that did more or less what 
you wanted. While not an entirely satisfactory piece 
of software, it was something anyone could use. 
Today we have several new application-generating 



languages for the Amiga that are both more sophisti- 
cated and simpler to use. A good example is INOVA- 
tronics' CanDo, which breaks down program creation 
into a process involving the generation of small mod- 
ules, or cards. (Think of the completed application as 
a deck of cards.) In using this kind of approach, the 
la)- programmer is working with modern program- 
ming practices — such as structured or object-oriented 
programming— without even being aware of it. (For 
a review of CanDo, and other interactive authoring- 
system software, see May '90. p. 12.) 

Just about anyone who can use a mouse can create 
a program with CanDo. The majority of program 
functions use requesters to get information about a 
task. For example, to create a custom window, you 
need only click on the window button and then define 
the size and number of colors you want by clicking 
on the pop-up Dimension requester. Or, to have the 
program load a previously created picture, simply 
select the picture from a file requester. 

As you can sec, using CanDo's high-level interface 
makes it extremely simple to create a custom screen 
and window or load an IFF image. Contrast this kind 
of ease of use with the time and effort it would take 
to write the numerous lines of C code required for 
the same task. 

While CanDo is primarily a requester-based sys- 
tem, many of its functions do require you to create 
a script in order to use them. These scripts are similar 
to more conventional programs in that they are a set 
of written instructions executed in a sequential man- 
ner. Like RAS1C, the commands and functions are 
very high level, but they are not as intuitive for the 
nonprogrammer as other aspects of CanDo. For most 
nonprograminers, however, learning to use the script 
functions of CanDo is much easier than trying to 
learn even a language such as BASIC. 

Look, Ma, No Code: The Icon Revolution 

While the CanDo interface certainly seems easy and 
intuitive, how about an entirely graphics-based ap-

unlike programming in any other language on [lie 
Amiga. There arc no scripts at all; instead, you use 
graphic icons to issue commands and requesters to 
input information needed by the program. (For more 
on AmigaVision, see "Welcome to a New Generation," 
[tin. '90, p. 18, and stay tuned for an AmigaVision 
tutorial coming up in a future issue.) 

An AmigaVision program looks exactly like a flow- 
chart. You place each command in position on the 
flowchart by using the mouse to drag the icon from 
its menu and place it in the desired position inside 
the How window. Once you acquaint yourself with 
the icons, it is possible to understand most of the 
program by simply looking at the flowchart. (This 
reminds me of the old programming joke that no 
comments were needed because the code was "ob- 
vious". AmigaVision comes very close to making such 
wishful thinking a reality.) 

Once you position them in the flowchart, vou must 
further define the AmigaVision icon commands. By 
double clicking on the icon, you bring up a requester 
with bullous, gadgets, and information fields specific 
to the icon. Using the mouse, il is very simple to 
define the requester — although even here some fields 
still require keyboard entry. 

What is striking about Amiga Vision's approach is 
that it combines two of today's most popular pro- 
gramming techniques. In some ways, it reflects the 
top-down approach of structured programming, be- 
cause with many AmigaVision applications it is pos- 
sible to write the program before you actually go in 
and define the specifics of the icons. For example, a 
specific action in the program might trigger a picture 
to be displayed, while another action triggers an 
animation or sound. You do not actually have to 
define the animation, sound, or picture while you 
are creating the overall program flow. These imple- 



mentation details can be decided on at a later point 
in the application development. 

.AmigaVision (and CanDo) can also be considered — 
at least to some degree— as an object-oriented lan- 
guage. For example, using our admittedly minimal 
description of objects and classes above, you could 
think of the icons as class definitions. The Anim re- 
quester is the general template for the "class" of "ob- 
jects" called animations, specifically defining the 
characteristics required for displaying and playing the 
animation. Once defined, the requester is an actual 
animation object whose fields contain information spe- 
cific to this object and the actions it can take. 

One point 1 want to make about all these new 
approaches to programming is that they are not, of 
course, for everyone or for every project. For most 
(although not all) commercial software development, 
conventional languages (C, Modula II, assembly) are 
better choices. Some programmers will categorically 
reject icon-based languages as gimmicks. Other con- 
ventional programmers, however, may find very 
good reasons to use one of the new multimedia lan- 
guages over other methods. In addition, ordinary 
users may discover ihey can now, finally, write the 
program they had always wanted to write but could 
never accomplish using more complex traditional 
languages. 

It may be some time before these user-friendly 
computer languages attain a level where they are as 
powerful as current development systems. But who 
knows, perhaps in the not-too-distant future, wc will 
simply tell the computer what we waul il to do and 
it will write its own program. That might sound like 
science fiction today, but with computers becoming 
increasingly more sophisticated and powerful, don't 
think it can't happen. If you don't believe me, think 
of all those techno-priests of the previous generation 
who sniggered into their while lab coats when some 
farsighted feller hinted at where computers might be 
in another 25 years, say about 1990! ■

TO PROGRAMMING THE AMIGA 

Investigate the routines of the system software, and 
you'll find the solution to getting more out of your BASIC and C programs. 



W 



HILE PROGRAMMING IS 

tedious and painful to some 
people (sort of like doing 
your (axes while having 
|a tooth drilled), the ex- 
perienced Amiga pro- 
' grammer probably finds 
it as challenging as unrav- 
' eling a good mystery game. 
The casts of programming 
capers don't include butlers, but 
you will find plenty of suspects in the libraries, which 
are the system software's groups of related, readv- 
made functions that control the Amiga's features. 

The main differences between programs— whether 
C or BASIC— on the Amiga and on other computers 
are in the sections that receive user input or display 
output to the screen. The input and output routines 
in standard BASIC and C have been geared towards 
a text-based console device. Traditionally, these lan- 
guages expect all input to come from the keyboard 
as a stream of text characters, and all output to go 
to the display screen or printer in the same kind of 
text stream. They also assume that the computer has 
nothing else to do but handle your program's input 
and output (no multitasking). 

The Amiga, however, can receive input from the 
keyboard as a stream of text characters or Rawkey 
codes, or from the mouse in the form of messages 
from the Intuition user interface about mouse move- 
ments, mouse-button events, gadget events, or menu 



selections. Your program can even receive input from 
other programs through a public message port. For 
the most part, output goes to a graphics display that 
you can set to a number of different display modes. 
On the Amiga, even text is treated as graphics and can 
be displayed using a variety of fonts, type styles (such 
as bold or underline), colors, and drawing modes. 

To help you access the machine's system-specific 
features, the Amiga's operating system provides li- 
braries of fairly high-level support for programmers, 
and both BASIC and C provide methods for incor- 
porating these functions into your own programs. 
The most important libraries reside in the Kickstart 
ROM, while some auxiliary ones are stored on the 
Workbench disk's libs: directory. For example, func- 
tions related to the mouse-driven user interface are 
in the Intuition library, while low-level graphics rou- 
tines are located in the Graphics library. 

Before you use one of the functions in a library, 
1 you first open the library to notify the system that it 
is in use and to retrieve the location of the library's 
base memory address for your program's reference. 
After you are finished with a library, you should close 
it to tell the system you no longer need it. 

Both Amiga Basic and C allow you to include Amiga 
system functions in your programs, but they do so 
in different ways. C contains few intrinsic commands 
and has always used external-function libraries to 
supply all input and output functions. Amiga C com- 
pilers, therefore, let programmers call Amiga system 
functions exactly as they would call external C func- i

tions, except Cor having to open and close the Amiga 
libraries. BASIC, however, relies on internal com- 
mands to provide all of its functions. The BASIC 
approach to expanding its functionality is to add new 
commands to the language. 

Amiga Basic contains many commands that pro- 
vide the same general functions as some of the Amiga 
system routines, but that use the terminology and 
syntax of BASIC, rather than that of the system rou- I 
tines. In many cases, the BASIC equivalents of the 
system routines are much easier to use than the 
original functions, but are also far more limited in 
their capabilities. Because the system contains so 
many functions, however, adopting them all would 
be too unwieldy. 

Amiga Basic tries to remedy this with Library and 
Call functions that allow you to use system functions 
within your own programs. The major problem with 
this alternate approach is that .Amiga system functions 
often require large data blocks as input, and the 
BASIC methods lor setting up such data blocks are 
all somewhat clumsy. 

Let's look at a simple example problem pro- 
grammed in C (Listing 1) and in .Amiga Basic (Listing 
2). The programs merely display some colored text

and dotted lines in each of the Amiga drawing modes 
on a low-resolution, 8-color screen. Although the two 
versions are similar in design and function, the BASIC 
code is much shorter, because some 'of the BASIC 
commands take the place of several Amiga system 
functions. In addition, the C version has to declare 
variables and define data structures that the BASIC 
version does not need. 

Gather the Suspects 

The programs are divided into three sections. In the 
initialization section, we do all the set-up work nec- 
essary for displaying graphics. In the C version, this 
means first opening the Intuition and Graphics li- 
braries with OpenLibrary( ) function calls. The In- 



tuition library contains the screen and window 
commands needed to prepare the display, while the 
Graphics library contains the functions that actually 
draw graphics and text on that display. 

Once the Intuition library is open, we can prepare 
the display with the OpenScreen( ) function. Think 
of an Intuition screen as a backdrop upon which 
output windows are opened. The screen defines the 
display mode for these windows, including the width 
and height of the screen, horizontal resolution (hi- 
res or lo-res), vertical resolution (interlaced or not), 
color depth (2-32 colors), and such incidentals as 
default colors and text font. Near the top of the 
program file, the NewScreen data structure (here 
called NewCustScr) specifies all of these items. 

After we open the screen, we can open an output 
window by using the OpenWindow( ) function. Each 
output window has many attributes, including the 
screen to which it is attached, starting size and po- 
sition on that screen, maximum and minimum sizes, 
window title, system and custom gadgets, and Intu- 
ition events (such as mouse movements and key 
presses) about which the window should be notified. 
We define all these parameters in the NewWindow 
data block, which we call NewWdw (following 
NewCustScr in the program). Now, we also set the 
color registers that will be used on this custom screen, 
using the LoadRGB4( ) command. I.oadRCB4( ) lets 
us load all eight colors at once from a list contained 
in the colormap array. 

The BASIC initialization sequence is similar, but 
differs on some key points. First, we use the Library 
command to open only the graphics library. Because 
the screen and window commands we need are built 
into BASIC, we need not open the Intuition library. 
For the Library command to work properly, however, 
a file called graphics.bmap must be located in the 
directory from which the BASIC program is run or 
in the Workbench's libs: directory. To create a graph- 
ics.bmap file, you must run the BASIC program 
ConvertFD (found in the Extras disk's BasicDemos 
directory). When the program asks you which .fd file 
to read, type: 

extras 1 .3:fd 1 .3/graphics_lib.fd 

and when it asks which .bmap file to write, reply: 
libsigraphics.bmap 

The next command is DEFLNG A-Z, which de- 
clares that all variables should be treated as 32-bit 
integers. This is a good practice when dealing with 
Amiga system functions, because these functions ex- 
pect input values to be 32 bits long. To open a custom 
screen, we use Amiga Basic's Screen command, which 
is similar to the system's OpenScreen( ) function. 
Instead of requiring a NewScreen structure with 13 
input values, however, the Screen command lakes 
just five input values, giving us control over width, 
height, color, depth, and mode, while using defaults 
for other values such as the text font. »-

The art of driving. 



Introducing the ultimate driving 
machine, the AE HD (high density) 
Drive, Applied Engineering's new high 
density 3.5 drive (above, at right). The 
first and only high density drive for the 
Amiga, it runs circles around the compe- 
tition. The FCC certified design supports 
both standard 880K and 1.44MEG 3.5" 
disks. The new AE Standard device controls 
both the high density mode and built-in 
electronic disk ejection. For running the 
new Amiga UNIX, the AE Standard 1.44 
MEG format is a virtual must. 

1.44 MEG capacity means you can stop 
playing diskette roulette. Simply store 
your large 2-disk application programs 
on one, high density disk and forget 
about fumbling for "sets" of disks. And 
storing files just became twice as easy 
too, because you'll only need half the 
number of disks. 

We also added performance features 

like an exclusive 2-way LED indicator 
that displays green for reading, red for 
writing. And a smooth, quiet electronic 



disk ejection to replace the clunky "punch" 
of other drive's ejectors. Since our electronic 
ejection is tied to the write/enable function, 
you can no longer accidently trash a disk 
by inadvertently pushing the eject button 
while the drive is writing. Our ejector 
waits until the drive completes the write 
and then auto-ejects the disk. 

Beauty AND brains. Aesthetically, the 
AE HD Drive is every bit as handsome as 
it is intelligent. We designed a high-impact 
ABS plastic case to protect the top quality 
SONY mechanism inside. 

For driving on a budget, we've designed 
a quick, quiet 880K standard 3.5" drive as 
well (above, at left). Incorporating a reliably 
quiet and trouble-free design, the AE 880K 
Drive™ sports a tough aluminum case, custom 
molded cable and an on/off disable switch. 

Both drives are compatible with all 
Amiga computers and feature complete 
daisy-chain capacity (from AE to another 
drive or vice-versa), MS-DOS compatibility, 
pass through connectors, FCC certified 
designs and full one-year warranties.

The Window command that we use to open an 
output window on this screen is, similarly, a limited 
version of the OpenWindow( ) function. It allows us 
to specify the screen to which it is attached, the size 
and title of the window, and the system gadgets that 
we want to attach, but does not let us receive event 
messages concerning these gadgets. As a result, if we 
were to include a close gadget, the user would be 
able to close our output window, but the program 
would never be notified that the window had been 
closed! The inability of Amiga Basic programs to 
receive event messages from their windows seriously 
limits the usefulness of the BASIC version of the 
Amiga windowing system. 

To close out the initialization routine, we set the 
screen-color registers, using the Palette command. 
This command is like the SetRGB4( ) system function, 
which sets one color register at a time, rather than 
LoadRCB4( ), which sets a number of them at once. 
As a consequence, we must repeat the Palette com- 
mand for each register we wish to set. Finally, we set 
up an array of text strings called Model, for the 
various messages we want to print. This corresponds 
to the textmsg array in the C program, but because 
BASIC lacks a means of setting values for a number 
of data items at once, we must set each siring value 
separately. 

Examine the Evidence 

The next section of the programs, ShowModes, is the 
one that performs the real work of drawing the text 



and graphics. First, it draws a filled blue rectangle 
on the screen. In the C version, we set the drawing 
pen to blue with the SetAPen( ) function, and use the 
RectFill( ) function to draw the filled box. In BASIC, 
we use a single Line command both to set the drawing 
color and to draw the filled box. 

Next, the programs prepare for writing text and 
drawing dashed lines in the various drawing modes 
by setting the foreground and background pen colors 
to red and green, respectively, and setting the line 
pattern to long dashes. In C, separate SetAPen( ) and 
SetBPen( ) calls are needed to set foreground and 
background colors, but in Amiga Basic a single Color 
command handles both. To set the line pattern in C, 
we use the SelDrPt( ) macro (which is defined in the 
include gfxmacros.h file), while in BASIC we use the 
Pattern command. 

Because the remaining graphics output is repeti- 
tive, it's drawn within a loop, a repeating block of 
program code. In both cases, nested FOR loops do 
the trick; for each of three blocks of text, the programs 
print two lines in each block. First, we calculate the 
vertical, or y, position; then we calculate a drawing 
mode. The actions are similar in both programs, 
although in the BASIC version, the y position is ex- 
pressed as text lines, while in C, the position is figured 
in screen dots, or pixels. (In this case, each text line 
is eight pixels high.) 

Next, we set the drawing mode, print a line of text, 
and draw a dotted line. Because BASIC lacks a func- 
tion for setting the drawing mode, the BASIC; pro- »

gram must call the SetDrMd( ) function directly, just 
as the C version does. For input, this call requires 
the mode number and a pointer to the window's 
RastPort data block. In BASIC, the Window(7) func- 
tion returns the RastPort address. The mode number 
specifies a drawing mode such as JAM1, JAM2, or 
Complement. 

In JAM 1 mode, the program uses the foreground 
color to draw the text. In JAM2, the text is drawn in 
the foreground color, and the background GO the text 
is drawn in the background color. In Complement 
mode, the text is drawn in the color whose pen 
number is the complement of that of the existing 
background color. (If this is hard to visualize, study 
Figure 1, showing the C program's output.) 

With the drawing mode set, the program now 
writes the text and draws the dotted line. In C, this 
requiresaMovef )call to set the pen position, aText( ) 
call to print the text, another Move( ) call, and a 
Draw( ) call to draw the line. In BASIC, we need only 
Locate, Print, and Line statements, because the Line 
statement combines both move and draw operations. 

Pronounce the Verdict 

After drawing the display, the program needs to get 
a signal from the user to end. In BASIC, the Sleep 
function suspends the program until the user presses 
a key or mouse button. Sleep does not give us any 
information about the event that ended it, though. 
It also seems susceptible to prior events, which is w r hy 
we use two Sleep commands in a row. The first one 
is terminated by events that have been stored up, 
while the second one does the actual waiting. 

In the C program, we use the WaitPort( ) function 
to suspend the program until we get an Intuition 



message. Because we specified when we opened our 
window that it would like to get both Rawkey and 
Mousebutton messages, either event will satisfy the 
\VaitPort( ) function. This example uses the Wait- 
Port( ) function in a fairly crude manner, as it tloes 
not check to see what kind of message it received. 
Unlike (he BASIC version, however, the C program 
can interpret the message it gets and use the infor- 
mation about mouse movement or key strokes for a 
productive purpose. When the programs get the sig- 
nal to end, both versions close the output window, 
the custom screen and the libraries they opened, and 
then exit. 

As you can see, adding Amiga-style input and out- 
put to your BASIC and C programs is relatively 
simple. Keep in mind, however, that while Amiga 
Basic's built-in Amiga functions make getting started 
easy, they are not ultimately powerful enough for the 
most sophisticated kinds of applications. For those, 
you will need to call the Amiga system routines di- 
rectly, just as you do when programming in C. 

The best source for further information about these 
routines is the Amiga ROM Kernel Reference Manual: 
Libraries ami Devices (S33.95, Addison-Wesley, Route 
128, Reading, MA 01867, 617/944-3700). Once you 
have learned how to send output to windows, and 
to receive input from menus, gadgets, mouse and 
keyboard, you'll be well on your way to becoming a 
master detective, writing programs with a distinctive 
Amiga flair. O

NEW MEANING 

OFTHE 
SOVIET BLOCK 



Now that Glasnost has redefined East 
West relationships. Spectrum HoloByte 
brings you a new way to think about 
Soviet blocks. 

First came TETRIS™, the game of 
fast thinking and quick reflexes. But 
just when you thought you had 
mastered TETRIS, the latest mind 
teaser from the USSR has been 
revealed. 

WELLTRIS™ takes you into 
another dimension as you attempt 
position falling blocks and shapes in 
rows and columns on the bottom grid of 
a three dimensional "well". The longer you 
play, the tougher it gets! 

TETRIS and WELLTRIS. Exciting new 
dimensions in Soviet blocks!

Hard Lessons: Solid Results 

Careful organization and maintenance of your hard-disk drive can pay big 

dividends. Here are five tips— with appropriate support utilities— 

to help you make the most of your investment. 



By Mike Hubbartt 



WITH THE PRICE of Amiga hard-disk drives drop- 

ping steadily, more and more users can afford the 
luxury of owning one. The problems involved with 
organizing and maintaining your hard drive, how- 
ever, still remain — no matter what kind of bargain 

E335SSS 



you drive in obtaining one. Here's a live-point "crash 
course," if you will, in procedures to follow and soft- 
ware tools to use for installing programs, protecting 
data, and improving overall performance when add- 
ing a hard drive to your system.

Organizing your hard-drive di- 
rectories efficiently will save vou 
an enormous amount of time 
and confusion. Keep similar 
programs grouped together in 
separate drawers (directories) 
so the root (main hard-drive) 
directory is not cluttered with 
too many files. Because the root 
directory is normally in the 
search path, you will waste a 
great deal of time if your pro- 
gram is looking for a file and 
first has to search through, say, 
300 root-directory files. You can 
also gel to an individual program much faster if you 
avoid such jam-ups in the root directory. 

In addition, you won't have to spend a lot of time 
backing up files if you organize well. For instance, I 
keep data for my word processor, database, and C 
compiler in separate subdirectories in their respective 
drawers, enabling me to make a backup of just those 
files on a daily basis. This avoids the time-consuming 
process of constantly making a complete backup of 
the hard drive, as I already have a master backup! 
.Although some people may favor doing a complete 
daily backup, I would rather spend my time working 
on the system rather than waiting for a backup to 
finish. 

As a working example, I have organized my 20MB 
hard drive, The Vault from Progressive Peripherals, 
as follows: I have two word processors, WordPerfect 
(plus WordPerfect Library) and Transcript, in a 




drawer labeled "Write." My 
database, Professional Data Re- 
trieve, is in a drawer called 
"PDR." Grouped in a drawer 
named "Science" are a number 
of related science programs 
consisting of Distant Suns, 
MathAMation, Doug's Math 
Aquarium, and Elements (a 
shareware program displaying 
the elemental periodic chart). A 
"Utilities" drawer holds tele- 
communications software, 
along with Disk Master and Disk 
Mechanic. The "Aztec" drawer 
contains my Aztec 5.0 C Compiler, while "CanDo" 
holds the multimedia-authoring system of the same 
name, As you can see, the choice of where to place 
programs is up to the user— but the principle of 
efficient organization remains the same. Because 
some of these programs are stored together in a single 
drawer, it is necessary to make extra draw r ers to hold 
these files. The easiest method is to single click on 
an empty drawer, select Duplicate and then Rename 
from the Workbench menu, and type in the drawer's 
new r name. 

DiskMaster (S49.95, Progressive Peripherals), con- 
tained in my Utilities drawer, comes in very handy 
when you are working with a hard drive. The pro- 
gram bandies bulk file management — which can be- 
come confusing when you are dealing with a lot of 
deeply embedded subdirectories. Because of its sim- 
ple point-and-click interface, DiskMaster lets you I

The art of memory engineering. 



Introducing the art of memory 
engineering. With the Amiga's practically 
unlimited potential, often the only 
barrier to greater productivity is a lack 
of memory. Adding expansion memory to 
your computer opens doors to new capa- 
bilities. But knowing how much to add 
and how to add it can be a real headache. 

For Amiga 2000s, 2500s and 3000s, 

Applied Engineering's new RamWorks 
2000™ (above, at right) is the definitive 
memory expansion solution. The board 
was engineered to incorporate 256K x 4 
dynamic random access memory (DRAM) 
chips. That's a significant improvement 
over chips used on other boards because 
it gives you growth-path choices. You can 
add memory in large increments or smaller, 
more affordable increments of 512K at a 
time. And you can add these small 
increments all the way up to 8 MEGs. 

Ease of use is also important Many memory 
expansion boards require the user to con- 
figure tiny switches or jumpers in a trial 
and error fashion to suit their particular 
hardware. RamWorks 2000 has an intuitive 



on-board feature that automatically con- 
figures your setup — making it much easier 
to install and upgrade. No switches, no 
jumpers — just add memory and go. 

We also designed RamWorks 2000 to be 
fully compatible with the A3000, so if 
you decide at some future date to upgrade 
your computer, you can switch the card 
over. RamWorks 2000 carries a five year 
warranty. Call for current pricing. 

For Amiga 500s with 512K, we designed 
the RamWorks 500™ (above, at left). 
Combining the functions of an internal 
512K memory card and clock card, RamWorks 
500 boosts the A500's available RAM to 1 
MEG. We incorporate 256K x 1 DRAM chips 
to make RamWorks 500 fully compatible 
with ALL A500 hardware and software, includ- 
ing pre-1989 machines. The built-in clock 
function automatically time and date stamps 
your files and a graphical diagnostic program 
checks for bad or improperly seated chips. 
Five year warranty With 512K installed $119. 

For the new A500 Professional with 
1 MEG built-in. Applied Engineering designed 
Timemaster 500™ (above, top). An easy 



way to add clock functions to your files, 
Timemaster 500 quickly attaches to the 
A500-P's expansion slot. Your files are then 
automatically time and date stamped for 
easy reference. Five year warranty $49. 

For ten years, Applied Engineering has forged 
a reputation for exciting and innovative 
peripherals. Built to our own exacting stan- 
dards of quality and reliability, our products 
are backed by the best warranties and the

Back It Up! 



Although complete backups of 
your hard drive on a daily basis 
may be superfluous if you have 
your directories organized 
properly, the importance of the 
right kind of backing-up pro- 
cedures cannot be overempha- 
sized. 1 learned the hard lesson 
of having a current backup of 
software on my hard drive when 
it crashed for the first time. If 
you haven't experienced a crash 
before, take it from me— it is 
definitely bad news! A hard 
drive has one or more platters 
that spin at a high rate, and the drive heads float 
above these platters while reading the information 
from them. Ahead crash occurs when the drive heads 
actually touch the rotating disks, physically damaging 
them and corrupting any data stored at the point of 
contact. A head crash can occur if the hard drive 

• is jolted or dropped during operation; 

• loses power and a stepper motor is used 

in the drive; 

• experiences controller failure. 

Because programs and data occupy more than a 
single sector, a bad sector may have more of a disas- 
trous effect than you might think— especially in a 
database or spreadsheet, where every bit of data is 
critical. Also, if a program has code stored on a bad 
sector, the program might not load at all, may give 
erroneous results in calculations, or might even crash 
your system. Not an entertaining prospect, to be sure. 

Back-up Programs Back-to-Back 

There are a number of trustworthy back-up pro- 
grams available, both commercially and in the public 
domain. Two that 1 use are Double Back— on the 
previously mentioned Disk Mechanic ($89.95, Lake 
Forrest Logic)— and Superback ($79.95, The Disc 
Company). Both work with easy point-and-click in- 
terfaces, and each lets you back up the complete hard 
drive or only those files that have changed since the 
last backup. Double Back, however, allows you to use 
more than one disk drive, while Superback sends 
files only todfD:. Both programs automatically format 
the disks holding the backed-up files. 

The recendy updated Quarterback {$69.95, Cen- 
tral Coast) also provides good back-up protection. 
Version 4.0 ($10 upgrade price to current Quarter- 




back owners) adds a number of 
new features, including a Print 
Catalog for creating archive re- 
ports after backups, a new 
"Slow" back-up mode for Ami- 
gas that can't handle fast back- 
ups, and several enhancements 
to the archive/restoration report 
function. 

It should be pointed out that 
neither Superback nor Double 
Back compresses the hard-drive 
data to save disk space. A com- 
plete backup of my 20MB hard 
drive (which is almost full— with 
only 700.000K free) requires some 24 disks. Double 
Back does back up floppy disks, while Superback does 
not. Of the two programs, I prefer Double Back, pri- 
marily because of the added benefit of getting other 
useful Disk Mechanic programs all for the same price. 
In any event, whichever utility you use, it is crucial 
to have a reliable backup of your software, because 
if you do have a crash, you will need to reformat 
your hard drive and reinstall your software. After my 
first head crash, it took five hours to reinstall all my 
software, plus a couple of days to test all the programs 
and to make the correct additions to my startup- 
sequence. If you choose to make do without a backup, 
save the s:startup-sequence (an ASCII file) to a floppy 
disk; this will save you a lot of time figuring out 
assignments and paths your programs may require 
if you need to reinstall your software after a crash. 
How often should you back up your hard drive? 
I have two complete backups. Some may question. 
Why two backups— isn't that a waste of disks? My 
first backup has all the programs I install on the hard 
drive initially, while the second is employed after I 
run an optimizer on the hard drive to enhance its 
performance (see section 3 below). If the hard drive 
goes down while you are working on it with the 
optimizer (which can happen if you run out of mem- 
ory during optimization or if a power outage occurs), 
you can reinstall the original backup and try again. 
Never work on a hard drive with software tools with- 
out a current backup of the installed software. 

After you back up the complete hard drive, your 
back-up procedures for data generated in your pro- 
grams should be much easier. As I keep separate 
subdirectories for data, a weekly backup of those 
subdirectories suffices. Why? The main software in- 
stalled on the hard drive rarely changes (except when i

Optimize = Faster Access! 



Although good hard-drive or- 
ganization alone speeds up ac- 
cess to programs and their data 
considerably, there are other 
tricks to make program loading 
even faster and more efficient. 
One of these is the process called 
"optimizing." Both floppy- and 
hard-disk drives store a given 
program or collection of data in 
sectors on the disk or platter; 
but information thai belongs to- 
gether is not necessarily stored 
together, which means that the 
drive head may have to spend 
considerable time searching over widely scattered 
sectors for the information before reading it into 
memory. This search time adds up when a large 
program's information is dispersed all over a disk. 
The optimization procedure relocates each program 
and its data to contiguous sectors of the disk or platter, 
thus decreasing the drive head's movement. The disk 
optimizers I recommend are B.A.D. ($49.95, Cen- 
taur) and Disk Mechanic's Tune Up (S89.95). 

Both B.A.D. and Tune Up do make a difference 
in performance, making program loading two to five 
times faster in many cases. (Large programs, such as 
WordPerfect and Distant Suns, benefit greatly from 




optimization — more so than 
such smaller programs as Tran- 
script.) Both Tune Up and 
B.A.D. can use a Workbench in- 
terface (by which you select the 
drive to optimize and then start 
the process by clicking on a 
gadget) or, if you wish, can em- 
ploy the CLI (where you specify 
the drive to optimize in the com- 
mand line). Either B.A.D. or 
Tune Up could easily become 
indispensible to hard-drive 
owners, although I prefer the 
latter simply because of the 
other useful Disk Mechanic utilities (such as Double 
Back) included in the one package. 

In either case, be prepared to spend some time 
optimizing your hard drive. It takes over four hours 
to complete the job on a 20MB drive the first time 
through— but only a little over an hour for subse- 
quent procedures. It does, of course, take much 
longer with larger drives, which makes it even more 
compelling to optimize on a regular basis. Neither 
program allows selection of only one physical area 
of the drive for optimization, although Tune Up's 
gadgets do let you process the complete directory 
tree or individual directories of the hard drive.

Despite all the careful organi-

and optimization, there are still 
pitfalls awaiting the hard-drive 
user. Locating disk errors can 
be a tricky process. Three pro- 
grams that can help you here 
are Dunlap Utilities' (S79.95, 
Progressive Peripherals) Verify-

Markbad, and the Doctor Ami

.Any hard drive can pick up 
errors over time, and these pro- 
grams will save you the trouble 
of reformatting (at low or high 
level) your drive when you get 
too many program errors for 
effective operation. A low-level 
format wipes out all program 
information on the hard disk, 
and it lakes more time than a 
high-level format (which is exe-

Disk-Caching Ov> u 1 d Catch On! 



When you move from floppy 

drives to a hard drive, improved 
program-loading speed is one 
of the major benefits you expect 
from your additional invest- 
ment. After you begin working 
awhile with your hard drive, and 
filling it up (not as difficult as 
you might imagine), you will 
probably start thinking about 
expansion— more room on the 
hard drive and faster program 
access. A disk optimizer does 
speed up a hard drive, but there 
are other considerations and 
other ways to accomplish what you need here. Disk- 
caching programs help speed up operations by stor- 
ing information previously accessed from a disk drive 
into memory locations that you designate specifically 
for such holding purposes. By doing so, you can 
access that information in significantly faster fashion. 
Most large Amiga programs are made up of many 
smaller programs called overlays, which are loaded 
in as needed by the program, A good example of a 
program that uses overlays is WordPerfect, whose 
spelling checker is loaded into memory whenever

no longer required, freeing up 
memory for other system uses. 
Such overlays can be stored in 
RAM, making the information 
quickly available without the 
need to access either a floppy or 
hard drive. 

For disk-caching software, I 
use the BlitzDisk program 
packaged with TxEd+ (S79.95, 
MicroSmiths), which works with 
both floppy and hard drives. 1 
have BlitzDisk installed in my 
startup-sequence as: 

device NOCHIP 



This provides a value of 250 buffers for the hard 
drive, which uses approximately 125K of memory 
for caching information accessed previously from the 
hard drive. BlitzDisk lets you specify both the 
amount— such as 250 buffers for the hard drive— 
and the type of caching for each drive— such as NO- 
CHIP. (Choose NOCHIP if the cache RAM should 
only be Fast Memory, or use DIRONLY if you want 
only the directory information stored in the cache.)

Although the Amiga market lacks a product with 
all the tools of The Norton Utilities in the IBM world, 
there are products out there that should satisfy many 
of the needs of the Amiga hard-drive user. Unless 
some Amiga developer comes up with a nearly per- 
fect, all-in-one solution, most users will probably wind 
up working with several of these utility packages at 
the same time. .And until such time as the ideal, it's- 



a-snap-to-use utility comes along, the importance of 
good hard-disk organization and maintenance habits 
will remain a top priority. ■

Tired of overstuffed disks ? These file-compression 
programs will help you free up valuable storage space. 




For whatever reason 
(to conserve storage 
space, lo upload to 
on-line services faster and 
save money, or to decom- 
press downloaded files), 
you have made the deci- 
sion to use a file-archiving 
program. Okay, but what 
do you do next? Your 
brother swears by ARC, his 
old standby, but the local 
BBS operator claims that 
other, newer contenders 
have long ago surpassed it 
Which program should 
you use: ARC, ZOO, 
LHARC, or PKAZIP? 
Does one stand above the 
rest, or are you better off 
using a combination of 
compressors? If so, which 
should you use when? 

Four years ago, the de- 
cision was much easier; 
your only choice was ARC 
(available on Fred Fish disk #70 or as file #5666 in PeopleLink's 
AmigaZone), which for the first time let Amiga owners combine 
and compact one or many files into an archive. The summer of 
1987 brought the first challengers: ZOO (Fred Fish disk #164, 
AmigaZone file #12241) and PAK (AmigaZone file #8896). 

ZOO improves on ARC in having the ability to archive files 
hidden inside a directory and in providing better file compression 
(or so everyone thought at first— see below for more on ZOO 



archive sizes), while PAK 
creates archives you can 
unravel by simply run- 
ning them from the CLI 
as you would with nor- 
mally executable pro- 
grams. ZOO gained con- 
siderable acceptance (with 
ARC not far behind) until 
the giants of the MS-DOS 
archiving world, LHARC 
(AmigaZone file #19961) 
and PKZIP (PKAZIP on 
the Amiga; AmigaZone 
file #19805), carried their 
feud over into the Amiga 
realm. 

The Proof Is in 
The Packing 

To help you sort out the 
choices, I tracked the big 
four's compression and 
decompression limes and 
the sizes of their archives 
for six sets of files in RAM. 
For the ARC tests, I also recorded decompression times for 
PKWARE's PKAX (AmigaZone file #13087), an unraveling utility 
for .arc files. I ran the tests twice— first on a stock Amiga 2000, 
then on an A2000 with Commodore's A2630 card (with both the 
FASTROM and CACHE options enabled via SetCPU). 

The six file sets represent an average cross section of data: 
Communicator version 1.34 is a popular public-domain terminal 
program; Moria version 3.0 is a PD fantasy role-playing game; *■

TFL is the June '89 edition of Chet Solace's Amiga 
BBS listing called The Final List; Woodland II, from 
Louis Markoya, is a ray-traced, interlaced, HAM IFF 
graphic; Twilight is a Jim Robinson VideoScape 3D 
animation in Anion format; and Sonix-Progressive is 
Tony Solomon's 90-minute Sonbc music collection. 

Consult the accompanying chart for a comparison 
of the performance figures. File sizes are listed in 
bytes, and times are stated in min:sec format. ARC 
tests marked N/A could not be completed, as the 
majority of files in the set had names that were longer 
than the 12-character MS-DOS standard to which 
ARC conforms. 

A quick look at the numbers shows that, contrary 
to popular belief, LHARC does not always create the 
smallest archives. PKAZIP bested LHARC on Com- 
municator and TFL. LHARC, however, usually wins 
on file sets containing graphics data (such as IFF 
files), beating PKAZIP by three to eight percent in 
these tests. PKAZIP's MS-DOS heritage handicaps 
the program on file sets with graphics, because the 
PKZ1P family is tailored for the most common types 
of MS-DOS data files— textand executable programs. 
PKAZIP also did not compress the Sonix-Progressive 
files as well as LHARC, because the set contains over 
150 files {half of which are smaller than IK), and 
PKAZIP needs to add more header information (used 
for identification at decompression) to each file than 
does LHARC. 

On the other hand, PKAZIP creates archives twice 
as fast as LHARC, and it unravels them three times as 
fast. Tests did not uphold the myth that LHARC per- 
forms much better relative to PKAZIP on an acceler- 
ated Amiga. The results here were inconclusive: While 
LHARC improved considerably on the 68030 Amiga, 
closely approaching PKAZIP's speed for the Twilight 
and Sonix-Progressive files, it fell further behind in 
comparison to PKAZIP on the Moria archive. 

ZOO, of course, can create and unravel an archive 
more quickly than any other program. ZOO's archive 
sizes, however, were usually 20 to 30 percent larger 
than those of LHARC. ZOO's terrible reputation in 
connection with IFF pictures also showed up in the 
tests: ZOO created an archive 30 percent larger than 
the original Woodland II file!

The biggest loser was ARC, which came in dead 
last on most of the tests. While it did compress the 
Woodland II picture almost as well as LHARC, it 
took slightly longer to do so. 

A Tight Decision 

For compressing files, ARC and ZOO obviously have 
been relegated to the shelf by LHARC and PKAZIP. 
PAK is still handy for BBS sysops, as it lets them 
upload compacted packages that can then be down- 
loaded and expanded by anyone, whether or not they 
have a decompression program. 

Picking a clear winner between LHARC and PKA- 
ZIP, however, is more difficult, because the issues to 
consider go beyond size versus speed. PKAZIP has 
other benefits on its side, such as adding 32-bit CRCs 
(Cyclic Redundancy Checks) to each file's header, 
thus providing greater data integrity. How much 
difference does this make? Keep in mind that one 
prominent Amiga developer recently banned the use 
of LHARC for in-house file transfers after finding 
that LHARC sometimes lost pieces of archived text 
files. More important for beginners, PKAZIP sports 
an Intuition interface, while LHARC uses a tradi- 
tional command line. To decompress a .zip file, you 
simply point and click, but you must type LHARC x 
filename. lzh to unravel an .lzh file. 

The easiest to use, PK\Z1P also has the best user 
support: PKWARE operates a BBS in Wisconsin. For 
the tinkerers and customizers, source code for 
LHARC is distributed free along with the program. 
PKAZIP is shareware (a S23 donation is requested) 
and more closely guarded; PKWARE does make the 
archive data formats for PKZIP/PKAZIP available, but 
does not include the source code with the program. 

Active uploaders be warned: Some boards police 
the use of certain compression formats. At this writ- 
ing, GEnie and CompuServe limit the use of .zip files, 
and BIX restricts both .zip and .lzh files. Fortunately, 
PeopleLink has no restrictions. Such limitations are 
not only premature, but can also discourage new 
users from telecommunications on the Amiga. For 
novices, clicking a few buttons on the PKAZIP screen 
is much easier than typing commands in the CLI. 
E-mail your sysop and demand the freedom to choose 
your archiving format. 

For users who want to compress files only to con- 
serve space, and don't care about speed and other 
factors, LHARC is the best choice. You will be doubly 
pleased with the results when storing mostly graphics. 
If you plan on doing a lot of downloading from 
networks and BBSs, I recommend keeping copies of 
all four programs in your C: directory. In that way, 
you can always decompress any interesting files yon 
find, including any new archiving challengers that 
might come along. ■

If you ever wondered just how smart you were 
when you bought your Amiga, get AmigaVision™ 




Remember your original reasons for getting an 
Amiga? CH course you do. Silly question. 

Well, fast-forward now to April 24th, 1990, the day 
Commodore introduced AmigaVision. j" 

AmigaVidion u an authoring system for a mere $149 that 
altomf the Amiga to live up to its full potential. 

The easy-to-learn, easy-to use iconsyou see up on the 
screen and on this page call up music, animation, text, 
video— in whatever order or even simultaneously— and 
create, well, any type of presentation or courseware. 

Also, AmigaVision takes full advantage of ARexx, 
your Amiga's file format standards and its multitasking 
capabilities. 

As 3'ou might imagine, you don't have to be a pro- 
grammer to turn your abstract ideas into reality. All you 
have to be is you. V* 1 



Can it extend the use of application software you 
already own? Is there multitasking interaction with 
other programs? Is it dBase III™ database compatible? 

Ye,.,.,.,, s , «,,.,,„,, g 

For business people, it can create presentations that 
persuade. For people in education and training, it can 
help create interactive instructional programs. For any- 
one, anywhere, it can liberate the way they communi- 
cate, whether they are delivering information or 
entertainment. CCH tfjy,J 

Call 1-800-627-9595 soon to find the location of your 
closest Amiga dealer. For you, its another confirmation 
of what you knew before most people: namely how smart 
Amiga is and how shrewd its owners were when they 
bought one.

HAM 

Shadow Painting 



STAYING WITH HAM and Digi-Paint 
(NewTek) a while longer, Accent this 
month again focuses on techniques relat- 
ing to the fundamental use of light and 
shadow. But while previous columns ex- 
plored Transparency settings and brush 
wraps as "automatic" ways of painting 
objects highlighted by apparent light 
sources, this time we will look at a sim- 
ple method of laying in more dramatic 
shadows by hand in order to define 
shape and volume. 

Casting the First Stone(S) 

For the illustration accompanying this 
column, I was tempted to use a more 
complex painting, but decided that a 
simplified demonstration painting would 
better clarify the technique. Rocks are a 
great subject for experimenting with 
shadows. If you do not live near a rocky 
landscape, gather stones from a road or 
chunks of cement from an empty lot. Ar- 
range these on your desk in different 
compositions and put a strong light on 
the display. Observe the shadows of the 
stones on the surface as you change the 
direction of the light. 

As an exercise, I once placed nine 
beach stones on a sunny shelf, rear- 
ranged them every morning for a 
month, and did a drawing of each new 
arrangement. Those thirty drawings 
gave me some of my most valuable in- 
sights into light and shadow. Stones are 
so varied in shape that a beginning artist 
with poor rendering skills can be free to 
focus on particular considerations such 
as light and shadow. If you feel frus- 
trated trying to paint portraits, take a 
break and try stones awhile. 

I painted the "Rocks" illustration with 
a very limited set of tools and the default 
palette— doing the base painting in the 
Range mode and all the shadows in the 
Darken mode. To provide a background 



for the stones, first paint sky and 
ground. The sky is a Range of light blue 
at one end and brown at the other. Ran- 
dom dither provides a nice blending of 
colors. Set the left and right Transpar- 
ency controls to the top, fully Opaque. 
Select the Horizontal Hotspot and slide 
it to the top of the Control window. Us- 
ing the Filled Rectangle tool, drag out a 
box from the top of the screen to a hori- 
zon line and let it fill. Keep your horizon 
fairly low on the page for pleasing pic- 
tures. Repeat the procedure for the 
ground with a new Range of colors. No- 
tice the interesting effect of using brown 
at one end of the sky Range. The sky 
then harmonizes nicely with the earth 
colors. 

To paint the basic form of the rocks, 
set the left Range color to light gray and 
the right to dark gray. Select the Point 
Hotspot and slide it to the extreme up- 
per-left corner of the Transparency win- 
dow, indicating a light source from that 
direction. Leave the Transparency sliders 
at the full Opaque setting and select the 
Filled Freehand tool from the Tools 
menu. You are then ready to paint some 
rocks. Learn to use keyboard shortcuts 
while you paint, such as the u key for 
Undo and the Escape key to toggle the 
menu on and off. Keeping your left 
hand on the keyboard and using key- 
board commands as often as possible will 
allow you to concentrate on painting 
without the distraction of continually 
moving the cursor away from the paint- 
ing to the menu area. 

Paint all the back rocks first so they 
look natural as the foreground rocks 
partially cover them. Keep the shapes

simple and vary the sizes. Try to keep 
them attached to the ground, especially 
as you move toward the foreground. Do 
this by flattening the bottom of the rocks, 
making it seem as though they are partly 
buried. The line you draw for the bot- 
tom of the rock is actually the line of the 
ground surrounding it. 

Stepping Back into the Shadows 
Notice that the Range of light-to-dark 
gray already gives a slight sense of di- 
mension to the rocks. It is a soft grada- 
tion of low contrast values across the 
surface. At this point, the rocks do not 
look very impressive, but the next phase 
will define form and add dimension. Se- 
lect the Darken mode from the menu. In 
the Transparency controls, set the left 
Hotspot slider about one-third of the 
way down. Set the right Edge slider 
about two-thirds of the way down. Leave 
I he Hotspot in the upper left lo make 
the darkness of shadow most intense at 
that edge. Using these settings, paint the 
shadow of the rocks on the ground. 
Trace the edge of the rocks fairly care- 
fully; then draw a simple irregular 
shadow extending away from the light 
source. Using Undo, experiment as 
much as you feel necessary to get a good 
shadow. This effect alone will make the 
stones seem more firmly fixed to the 
ground. 

Now comes the fun of shading the 
rocks themselves. Set the Hotspot close 
to the center of the red ball in the Trans- 
parency controls. This softens the edges 
of shadow areas just slightly, although 
you still want them crisp for this exer- 
cise, because the outline of each shadow 
will define the surface of the stone. In 
your mind, trace over this surface as you 




In "Rocks," the base painting was done In Dlgl-Palnt's Range mode and the shadows In Darken 
mode. Notice the near-black areas ("optical darks") In some of the corners of the darker shadows. 



draw a shadow area in the Filled Free- 
hand mode. This same technique would 
apply to portraits, where your imagina- 
tion guides a shadow line around a 
cheekbone, over the cheek, and finally 
under the jaw to vanish. Imagine the 
same character of contours in the rock as 
you work. 

Keep your first shadows simple 
shapes, as in the example. Select a few 
areas of the painting where you want to 
push the space back into deeper shadow. 
Make second, and even third, shadows 
in these areas. Down in the corners of 
two or three of these darker shadows, 
you can create "optical darks" by making 
successively smaller shapes that darken 
the "corner" to near black, as you see in 
the illustration. Be sparing with optical 



darks; but including a few of them in a 
painting will make the space "pop." 
When you feel comfortable with shadows 
on simple rock shapes, pull some old 
artwork into Digi-Paint and try using this 
simple Darken technique to add depth 
and dramatize the forms. ■

Back to Basics 
Part 7 

Our AmigaDOS experts wrap up their miniseries for new 
users with some final Shell commands. 



By Mark L, Van Name and Bill Catchings 



AT THE END of last month's column, 
we promised to reveal the bigger story 
behind our simple trick for stopping a 
command's output. This month, we 
make good on that promise, and show 
you a few of the most important Shell 
commands as well. 

When you type a space to halt a com- 
mand's output, what you are really 
doing is beginning a new command. The 
Shell halts the output of the current 
command so that you can see the one 
you are typing. This ability to enter one 
command while another is running is 
known as "type-ahead." If you type an 
entire command and then press ENTER, 
the Shell finishes the command that was 
already running, and then immediately 
starts on the one you just entered. 

In some instances, you may change 
your mind about entering another com- 
mand. If so, you can delete the charac- 
ters you have already typed by using any 
of the command-line editing tricks we 
covered in the past few columns. When 
you delete the last character, the Shell 
recognizes that the command line is 
empty, and it gets on with the stalled 
command. This explains why the space/ 
delete trick presented last month works: 
The space bar stops the output as the 
Shell waits for a new command, and the 
Delete key removes that space, inform- 
ing the Shell that you will not type a 
command after all. 

One nifty feature of the Shell's type- 



ahead facility is that all the command-ed- 
iting and history-buffer features are at 
your disposal while you are entering this 
next command. For example, hitting the 
Cursor Up key (f) while a command is 
running not only stops that command's 
output, but also allows you to see the 
previous command in the history buffer. 

Changing Directories 

So far, we have concentrated on differ- 
ent techniques for entering and editing 
Shell commands in general. But what 
about the commands themselves? Al- 
though we do not have room in this col- 
umn to cover all of the Shell's 
commands— there are over 60— you can 
get by nicely knowing only a few. 

We have already mentioned the three 
commands that give you information 
about what is on your disks: INFO pre- 
sents the name and amount of free space 
on every disk in your Amiga, while DIR 
and LIST display information about the 
files in your current directory. To move 
to a different directory, you need a new 
command, CD (for Change Directory). 

CD is the Shell's equivalent of opening 
a Workbench drawer. If you give it the 
name of the directory you want to enter, 
it puts you in that directory. For exam- 
ple, to enter the C directory, which holds 
the Shell commands, enter 

CD C 
(This assumes you're in the top, or root, 



directory of your Workbench disk.) 
Doing a DIR or LIST now shows you 
the names of all the Shell commands. 

Like the drawers in Workbench, The 
Shell's directories on a disk form a hier- 
archy. A directory can contain other di- 
rectories, each of which can in turn 
contain further directories, and so on. 
The top of the heap is the root directory 
of each disk, the name of which is simply 
the name of the disk itself. 

The CD command gives you several 
ways to move around in this directory 
hierarchy. In its simplest form, as in the 
example above, it lets you enter any di- 
rectory within the current directory. To 
move up one level in the hierarchy, use 
the slash (/) special character. For exam- 
ple, to move into the S directory that is 
within the root directory, enter 

CD/S 

The / moves you to the root directory, 
and then the S takes you into the S di- 
rectory. You could also have done the 
same thing with two separate commands: 

CD/ 

CDS 

Another way to move to a directory is 
to jump directly there by entering that 
directory's "full pathname." A full path- 
name starts with a disk name and then 
lists every directory you must enter to 
reach your goal. The slash separates the 
names of those directories. Thus, you ►

could enter the Workbench's S directory 
directly, no matter what directory you 
were in, simply by typing 

CD WORKBENCH 1.3:S 

In place of the name Workbench, you 
can also substitute the name of the drive 
in which that disk is currently held. For 
example, if your Workbench disk is cur- 
rently in your Amiga's internal drive 
(Shell name DF0:), you could get to S by 
typing 

CD DF0:S 

These variations on the CD command 
will work no matter how complex your 
directory structure. For example, the 
Workbench disk contains a directory 
named FONTS, which in turn contains a 
directory named RUBY. To enter RUBY 
from the S directory (where the last com- 
mand put you) you could use any of 
these CD commands: 

CD WORKBENCH 1.3:FONTS/RUBY 



CD DF0TONTS/RUBY 



CD /FONTS/RUBY 

or, taking the slow, one-step-at-a-lime 
approach, even: 

CD/ 

CD FONTS 

CD RUBY 

Basic File Manipulations 

Once inside a directory, you can perform 
a number of basic — and consistently use- 
ful—operations on the files contained 
there. The simplest and easiest one is to 
run those files that are programs. Simply 
type the file's name. You have already 
run programs, perhaps without knowing 
it, because every Shell command is ac- 
tually a small program. 

Another common operation is to see, 
or TYPE, the contents of a file. If you go 
back to the S directory and do a D1R, 
you will see several files, most of whose 
names include STARTUP. These files 
contain Shell commands that different 
parts of your Amiga run when they start. 
To see what's in the file SHELL- 
STARTUP, which the Shell runs every 
time you start it, enter: 

TYPE SHELL-STARTUP 



I' II I L E 

(To understand the commands in that 
file, you will have to do a little more re- 
search—but let's ignore them for now.) 

TYPE will work on any file, but you 
will be able to read its output only if the 
file contains plain text. Try TYPE on a 
program file, for example, and your 
screen will fill with garbage. 

Two fundamental file operations re- 
main: copying and deleting— the com- 
mands for which (COPY and DELETE, 
respectively) are certainly straightfor- 
ward enough. To make a copy of the 
SHELL-STARTUP file, enter ' 

COPY SHELL-STARTUP TEMP 

The file named TEMP now contains the 
same text as SHELL-STARTUP. If you 
find it helpful in remembering which file 
the Shell is copying to which other file, 
you can add the optional word TO, as in 

COPY SHELL-STARTUP TO TEMP 

To delete the temporary file that you 
just created, enter 

DELETE TEMP 

Be very careful with this command, how- 
ever, as its effects are final; once you de- 
lete a file, it's gone. 

No Next Time 

With the information we have discussed 
in this "Back to Basics" series, you're 
ready to take on the Shell and the rest of 
its commands. As always, the best way to 
learn how each command works is to 
read its description in the AmigaDOS 
manual and then play around with it. Be 
sure, of course, to restrict your experi- 
menting to a copy of your Workbench 
disk; keep the untouched original in a 
safe place. If anything goes wrong, you 
can always pull out your original disk 
and start over. 

We won't be be with you for the rest 
of that learning experience, however, be- 
cause after 4 years and 39 columns, this 
is the last info.phile. You will still be able 
to find us in the pages of Amiga World 
from lime to time— look for our in-depth 
analysis of AmigaDOS 2.0 in upcoming 
issues — but this column is history. Take 
care, and enjoy your Amiga! ■

Information and Ideas on Amiga Programming 



Graceful Exits 




By Robert J. Mical 

WRITING A PROGRAM that behaves well in an er- 
ror-free environment is relatively easy, if you can 
find such a setting. Errors do crop up, and as a pro- 
gram grows in complexity, it becomes increasingly 
difficult to exit gracefully when an error or abort 
condition arises. Past frustrations have helped me 
evolve a programming style in which I construct pro- 
grams to exit cleanly back to the system, no matter 
what caused the exit and whether the program ruli 
was partial or complete. A discipline as much as a style, 
its Mm < ardinal i tiles are: 

• Systematically track which resources have been al- 
located and systematically free them all. 

• Always check for error conditions and react to them 
immediately. 

The hardest part of following the discipline is being 
consistent, making sure that you always write the 
code as you are supposed to. Once you get into the 
rhythm of taking the required steps, however, it be- 
comes natural, and you will automatically create ro- 
bust, crash-free code. (While the examples here are 
in C, the concepts and style apply to all languages.) 

As you will see, I am a proponent of keeping 
everything simple, even when it means doing things 
the long-winded, safe way rather than taking short- 
cuts. The easy-to-understand way often translates into 
the fat way, but the convenience, readability, and 
aesthetic completeness of coding "in long-hand" are, 
in my mind, well worth the small increase in code 
size and decrease in performance. You can always 
slim down the code during alpha testing. 

Under this simple, long-hand programming, my 
main programs typically look like this: 

VOID main ( ) 



If (lnit( )) DoMainTask( ); 
CIoseEverything( ); 



} 



Even my mother could understand it: First, Initj ) 
performs the program's initializations, including the 



attempt to allocate system resources. If any one of 
the initializations fails, then Init( ) returns the BOOL 
value EAL.SE. If all of the initializations were suc- 
cessful, then Init( ) returns TRUE. If Init( ) is suc- 
cessful, then we DoMainTask( ). finally, in all cases, 
we CIoseEverything( ) to close and free all things, 
returning allocated resources to the system. 

Main( ) is also a micro-example of the graceful exit 
discipline. In Init( ) and DoMainTask( ) we get the 
resources, and in CloseEverylhing( ) we give them 
all back. In addition, the program abandons further 
execution as soon as it delects an error [don't 
DoMainTask( ) if Init( ) fails]. Let's look at some ex- 
ample Init( i and CloseEverthing( ) routines: 

,'* Declare resource global variables to have NULL values *■' 

struct IntultionBase "IntuitlonBase = NULL; 

struct Window *WorldWlndow = NULL; 

struct Remember *GlobalKey = NULL; 

BOOL lnit( ) 

/* Returns TRUE if all inits succeeded, else returns FALSE */ 

{ 

BOOL retvalue; 

/* Set to return FALSE until we're sure all is well */ 

retvalue - FALSE; 

/* Do Initializations. If any one fails, goto DONE */ 

If ((IntultionBase = (struct IntuitlonBase *) 

OpenLibrary( "lntultlon.llbrary",0)) = = NULL) 

{ 

printff'error: couldn't open intuition llbrary\n");

AMIGA 500 NOW H COMPATBU 

The Power PC Board has all the following features for your Amiga on one 
board, and it fits in your memory expansion slot of your Amiga 500: 

Imagine the speed of an 8 MHZ Turbo XT with a NEC V30 Chip, inside your Amiga 500. Never worry about ram, The board is 
packed with 704K and also has an additional 64K EMS to speed you on your way with all your applications. To help you along 
we have included the complete Microsoft Dos 4.01 with all manuals, M/S Dos Shell, GW Basic and Learning DOS (Value $199). 
In PC mode we use Phoenix Bios to insure the highest level of compatibility with your software. You can also use your serial port, 
parallel port, joystick port and mouse in PC mode. As if that is not enought.... Hercules/CGA and Monochrome graphics support, 
with your choice of colors and shades. Does it have a clock? Of course! Plus, support for your internal 3.5" drive and external 
drives! That's right, any Amiga external drive 5.25" or 3.5" will work in PC mode! We also include a Spreadsheet, Database and 
a Word Processor. In Amiga mode the Power PC Board has a clock, 512K ram expansion, and also gives you additional 512K ram 
drive. When in Amiga mode the PC side is totally transparent, and in no way effects it's operation. To aid you in moving your 
files between PC and Amiga we have included Cross Dos ($35 value).

Installation of the POWER PC BOARD is simple, No screwdriver, no soldering iron, and no technical knowledge is 
necessary. Just turn over your A500, open the expansion door, slide the POWER PC BOARD into the connector, 
and close the door. You are now the owner of an A500/PC-XT. Installing this board does not void your guarantee. 
No extra power supply required, thanks to the most modern engineering in CMOS and ASIC technology.

/* We opened the library. Did we manage to allocate 
* any other Intultlon-speclfle resources? */ 
if (WorldWindow) 

{ 

CloseWindow(WorldWlndow); 

WorldWindow = NULL; 

} 
FreeRemember(&GlobalKey, TRUE); 
CloseUbrary (Intuition Base) ; 
IntultionBase = NULL; 
} 



} 



As the example shows, you can use global variables as 
indicators to track which resources have been allo- 
cated. You start by explicitly initializing your system- 
resource global variables with NULL values. Variables 
declared in this way will have non-NULL values only 
if system resources have been allocated. By detecting 
whether the value is non-NULL, you can determine 
whether a resource needs to be freed. 

Consider the IntuitionBase variable in the above 
example. If IntuitionBase is NULL, then the library 
was never opened, and the Intuition-specific resources 
can be ignored. If IntuitionBase is non-NULL, then 
the library was opened successfully, so you must close 
it. In addition, you should check the Intuition-specific 
variables for non-NULL values, and, if some are 
found, you must free their resources, too. 

Notice that I set my global variables back to NULL 
after I freed the resources associated with them. If 
you're sure that your program will never do anything 
else after you call CloseEverything( ), then this is 
unnecessary. I'm never sure, however, that I'll 
remember tomorrow the things I promised myself 
today. Tomorrow I may accidentally call CloseEvery- 
thing( ) more than once when exiting, or I may think 
to use CloseEverything( ) to effect a cold restart of 
the program. So, choosing to do things the fat, safe 
way, I reset the variables to NULL. Tracking re- 
sources this way is part of the rhythm of this graceful 
exit style. I follow this rhythm, always following the 
rules the same way, and it always works. 

The philosophy for error handling is: Always detect 
and report error conditions, and no matter how 
deeply nested your routines become, always leave 
yourself a clear exit path where no more program 
logic will be executed should a fatal error be 
encountered. 

There are low-level routines that check for errors 
in the system (couldn't open a given file, couldn't 
allocate memory) and higher-level routines that check 
whether the low-level routines failed. Low-level rou- 
tines always return a value that indicates success or 
failure (BOOL routines would return TRUE or 
FALSE, while a memory-allocation routine would re- 
turn a valid memory pointer or NULL). When a low- 
level routine finds an error, it prints an error message 



and returns a failure result. Higher-level routines 
may themselves return a value that indicates success 
or failure, or they may simply cease execution and 
return as soon as an error occurs. The higher-level 
routines usually don't print an error message. 

For example, a general-purpose memory-alloca- 
tion routine could be written to print an error mes- 
sage on failure as below: 

/* These resource global variables are NULL unless 

* their associated buffers have been allocated. */ 
UBYTE 'BuflPtr = NULL; 

UBYTE *Buf2Ptr = NULL; 

UBYTE *XAIIocMem(size, types) 

LONG size, types; 

/* Tries to allocate specified mem, prints error message 

* on failure, returns pointer to memory or NULL */ 
-1 

UBYTE *ptr; 

if ((ptr = AllocMem(slze, types)) = 
printf("error: out of memory\n"); 
return(ptr); 



NULL) 



} 

BOOL AllocBuffers( ) 

/* II all buffers are allocated, returns TRUE, else FALSE */ 

{ 

BOOL retvalue; 

retvalue = FALSE; 

if ((BuflPtr = XAIIocMem(BUF1_SIZE, BUF1_TYPES)) 
= = NULL) goto DONE; 

If ((Buf2Ptr = XAIlocMem(BUF2_SIZE, BUF2_TYPES)) 
= = NULL) goto DONE; 

retvalue = TRUE; 
DONE: 

return(retvalue); 
} 

and add these statements to the CloseEverything( ) 
routine: 

If (BuflPtr) 

{ 

FreeMem(Bul1 Ptr, BUF1_S1ZE); 

BuflPtr = NULL; 

} 
if (Buf2Ptr) 

{ 

FreeMem(But2Ptr, BUF2_SIZE); 

Buf2Ptr = NULL; 

} 

You will notice in the AltocBuffcrs( ) and Init( ) rou- 
tines that I've used the dreaded Goto command, 
which often causes contention among programmers 
because it's against the "structured" style of pro- 
gramming. Actually, the Goto is the only non-struc- 
tured aspect of this style, and I use it in a structured 
way. In both styles, the program logic always flows 
through routines from top to bottom, except for t

the for( ) and uhile( ) loops. In this style, the Goto is 
allowed as long as the destination is below the com- 
mand, thereby maintaining the downward flow of 
control through the routine. Both styles avoid the 
nightmare of spaghetti code. Consistent use of the 
goto makes the code easier both to write and to 
understand. 

Let's examine the error-return routine more 
closely. When a routine is going to return a result 
that could indicate an error, as in AllocBufler.s( ) and 
Inil( ), the return result variable is initialized to a 
failure result at the top of the code. Any error within 
the body of the routine causes control to go to the 
end of that routine, where the error result is returned. 
Only if everything goes well is the return variable set 
to a successful result and then returned. 

The error-return routine is one of the basic build- 
ing blocks of this graceful exit style. Knocking out 
BOOL functions as a matter of course is part of the 
rhythm. I create these error-return routines so often 
that I have defined a function-key macro in my fa- 
vorite text editor (Cygnus-Ed) in order to add the 
body of a BOOL function to my source code. I tvpe 
in the following 

BOOL Mumble( ) 

{ 

} 

and then hit a function key. which adds a bunch of 
text to create this: 

BOOL Mumble( ) 

{ 

BOOL retvalue; 

retvalue m FALSE; 

retvalue = TRUE; 
DONE: 

return(retvalue); 
} 

El Voiih. Then 1 fill in the body of the routine, using 
"goto DONE" whenever an error has occurred. Be- 
cause I do this with every routine that could abort 
due to a failure, an error result can easily be prop- 
agated all the way back to the top— with no more 
program logic being executed on the way— no matter 
how many levels deep I get into routines calling other 
routines. 

You may think you'll never look at a piece of cock- 
again, but sometimes, then, you're tormented by it 
for years to come. So discipline yourself to make 
safety-coding techniques like these a natural part of 
your programming style. You'll be a happier and 
better programmer if you do so. ■

THE GAME PRESERVE 







Drakkhen and the Chamber of the 
Sci-Mutant Priestess 

By Peter Olafson 

EVERY SO OFTEN adventure 
games arrive that change the 
way we think about play and 
the Amiga. Following the 
ground-breaking traditions of 
The Hard's Tale, Faery Tale 
Adventure, Ultima IV, and 
Dungeon Master, Drakkhen 
(from Data East's Draconian 
line) is a massive 3-D quest to 
save the dragon kingdom 
from destruction. 

Few detailed 3-D worlds are 
as unfettered by the machine 
or as alive with possibility as 
Drakkhen's. This is the first 
game I've seen with a 360-de- 
gree perspective rendered in 
something more elaborate 
than standard polygon-fill 
graphics and in which both 
animated characters and 
monsters appear in your main 
travel window, imparting a 
you-are-there immediacy. The 
surface of the dragon island 
consists of four distinct ter- 
rains—desert, steppe, swamp- 
land, and arctic waste- 
rendered in basic geometric 
shapes and decorated with 
trees and shrubs handed 
down from Space Harrier. 
(Thai's a compliment.) 

The interiors of the many 
castles are drawn in dusky de- 
tail. Here, in the meat of the 
game, you have almost total 
freedom of action. You can 
send each character on an in- 
dividual mission or choose one 
to lead the others. Hint: When 
possible, stay together. . . 
unless you want to face alone 




Can you save yourself, let alone the dragon kingdom? 



the seemingly endless array of 
bizarre creatures— lizards, 
Chinese dragons, vector- 
graphics men with swords, 
and a huge red silhouette 
murmuring "I love you" in 
both female and male voices. 
You'll die often, and you'll en- 
joy every moment of it. 

The game pays great atten- 
tion to the fine points. Sounds, 
in excellent stereo, appear to 
be place- and lime-sensitive. 
The puzzles are sinister and 
logical. Horizons change color 
even when you watch from in- 
doors through windows. 
Buildings grow subtly larger 
as you approach. Monsters 
know when to run, if not 
when to fight. If you want to 
see exactly how fast your 
Amiga can fly, try using a tele- 



porter. I've yet to see a flight 
simulator move this fast and 
preserve this much detail. As a 
graphic engine, Drakkhen is 
staggering. 

As an adventure gaming sys- 
tem and a scenario, however, 
it wants a bit of fleshing out 
and articulation. For example, 
the game claims to have more 
than 200 spells; actually it has 
200 on-screen "visualizations" 
of the 23 spells documented in 
the instructions. Casting most 
of them is easy enough once 
you recognize their runic 
spellings: Just click down a list 
and push the right mouse but- 
ton while pointing at the char- 
acter. In combat, they can be 
cast automatically and there- 
fore accurately. In peacetime, 
however, the success of healing i 



Crib Notes 

By Peter Olafson 

• THE WEAPON STORE off to the 
north at the start of Drakkhen (Dra- 
conian, S59.95) does have some nice 
stuff, but if you think it's vastly better 
than what's in the first castle, you're 
not being thorough enough there. Did 
you really fake a look around the 
prince's room? Don't be frightened of 
him; he's just sort of a twitchy guy. 
Yeah, that's it. Take it, take it. (Then 
go outside, save, come In, take it 
again, and so on.) Don't chat up the 
prince much; he'll chase you out with 
spells. You should leave his place 
armed to the teeth. Make a point of 
raiding the temple (second floor on 
the right) to replenish your stock of 
magic items. You should be able to 
enhance the critical stats of each 
party member by the time you leave. 
Stock up on keys, too, as you can use 
them interchangeably. 

Finding his sister's castle, as the 
prince Instructs, is a bit tricky. Yes, 
It's to the east, but which way is east? 
Well, it's where the sun comes up, 
and If the sun isn't handy, the moun- 
tains on the eastern horizon are a little 
different from the others. The trip Is 
not a straight shot, however; your 
route is blocked by a north-south line 
of glowing while triangles. Don't try 
to cross them (though It's an Inter- 
esting way to die); make an end run. 

When you get back, the prince will 
send you north to the Prince of 
Water's castle. Once again, his direc- 
tions are sloppy. It's really west, 
north, west (around the Inn), and then 
north again. He neglects to mention 
that the castle's drawbridge will 
quickly turn your party into a bloody 
pulp, as well. One particular spell Is 
called for here. While no spell is spe- 
cific to the task, one has the right 
effect. It's the only logical selection. *■

GAME 



PRESERVE 



spells relies heavily on precise 
positioning of your characters. 
Reeling them off with any au- 
thority is difficult, and the 
documentation is mute on the 
subject. (Filling empty flasks 
without drowning a character 
is equally challenging.) 

Character control indoors is 
another sore point. The ad- 
venturers do a decent job 
finding their way around fur- 
niture without your help, but 
they can also stumble about as 
though they're playing soccer 
with an invisible ball. You have 
to click the mouse on a clear 
section of floor to get them to 
stop fidgeting. 

Drakkhen is a throwback in 
certain respects. Your quest to 
collect the eight dragon gems 
really isn't much more than a 
treasure hunt. Experience is 
gained mainly by beating up 
on everything in sight, and 
character interaction seems a 
bit archaic in these days of 
non-player characters with 
multiple-word triggers. You 
can't do more than "greet" 
and "question," and in most 



cases, the burbling little men 
beside the road come right out 
and tell you their life stories. 
(Repeated questions and a 
sheathed sword sometimes pay 
off.) Finally, the manual needs 
an orientation section; starting 
Drakkhen cold is rather like 
being dropped out of a heli- 
copter into a war zone. I'd 
gladly trade in the fantasy 
miniature that came in the 
box for even a partial map or 
an on-screen compass. 

These shortcomings, how- 
ever, can be addressed in the 
promised sequel. Even with 
flaws, Drakkhen is an out- 
standing technical achieve- 
ment, a compelling adventure, 
and an audio-visual feast. 

If you'd like a more com- 
pact and polished game, try 
Draconian's: Chamber of the 
Sci-Mutant Priestess, Drak- 
khen's impressive companion 
release. It's essentially a puzzle 
game in adventure clothing, 
with a wickedly smooth 
graphic interface. You can 
click the mouse virtually any- 
where and bring up a menu of 



options that's mounted on a 
brain, of all things. Even bet- 
ter. Chamber is that rare 
game in which the computer 
intermediary is almost invisi- 
ble. After a while, you'll find 
you're doing all your thinking 
with your mouse. 

You have to solve live or- 
deals to free the beautiful 
goodie-goodie Sci-Fi and 
thwart a plot by the lizard- 
faced Protozorqs. It's all great 
fun, and, while five puzzles 
may sound like barely an 
afternoon's work, you won't 
finish this game quickly. Most 
solutions aren't at all obvious. 
You'll always find something 
to manipulate or animate, 
someone to talk to, or some- 
thing to make you laugh. A 
light European wit is at work 
in the responses, and 1 defy 
you to read the docs with a 
straight face. 

I heartily recommend both 
these newcomers. ($59.95 each,

Waterloo 

By Kevin C, Rohrer 

THE DATE: JUNE 18, 1815. 
The place: Belgium. The 
French dictator Napoleon 
Bonaparte has returned from 
exile and rebuilt France's La 
Grande Armee. The Allied 
armies are responding by mov- 
ing to invade France. Unfortu- 
nately for them, Napoleon is 
aware of their plans and is 
moving to intercept. The two 
closest armies are under the 
English Duke of Wellington 
and the Prussian Blucher. 
Bonaparte beat Wellington 
at La Belle Alliance and 
Blucher at Ligny, and hopes 
to finish off the English near 
the town of Waterloo. With 
SSI's new war game, Water- *■

Issue your commands, then trust your corps commanders' skills. 



This castle is much tougher and 
longer than anything you've dealt with 
so lar. For now, don't waste time on 
doors you can't open. (They're prob- 
ably broom closets. I'll let you know 
later.) Do pay attention to doors you 
can't always see. There's more here 
than meets the eye; if you haven't 
leleported, you haven't seen it all. 

• Those of you having trouble with the 
steering in Hard Drivin' (Domark, 
$49.95) should remember to watch the 
speed limit signs (they're there for a 
reason), and to steer with small, in- 
cremental mouse movements. That's 
all that's required; anything else is 
likely to send you into off-road 360s 
in a hurry. You'll eventually learn to 
switch off between the accelerator 
and brake on the fast track. 

• To Valerie Kilgallon, who's out hunt- 
ing for a wick for the bomb at the end 
of Leisure Suit Larry II: Looking for 
Love in Several Wrong Places (Sierra 
On-Line, S59.95): You are picking up 
everything not nailed down, right? If 
so, it's the only combustible item in 
your Inventory. If not, well, It's in 
"plane" sight. 

• Is your town not growing too slowly 
in Sim City (Maxis, $44.95)? Don't tax 
for 11 months of the year. The Sims 
are all nasty little conservatives, and 
1hey love not having taxes. The city 
will grow like a weed. Come Decem- 
ber, however, tax them into the 
ground— to the tune of, say, 20 per- 
cent. You'll collect a bundle in Janu- 
ary. When the budget box turns up 
that month, pretend you're running for 
re- el Oct ion and eliminate the taxes 
again, Sims have a short memory, and 
they'll flock to your city once more. 

• You can get rid of the rocks mess-

on the blower (Galnet) to them. You

• Michael Smith of Belleville, Ontario, 
writes that when he's playing Falcon 
(Spectrum Holobyte, $49.95) at the 
Major level, he keeps crashing with- 
out explanation while landing— even 
though he's doing everything right. 
Mike, did you take any damage during 
the mission? An early version of Fal- 
con has a bug that causes a crash 
landing If you're at all shot up. it's 
fixed In version 1.1, which also makes 
the landing process easier in general. 
II you're using 1.1, the only require- 
ments for a safe landing are a speed 
of under 300 knots, a climb angle be- 
tween 25 and 18, and a banking 
angle of less than 20 degrees either 
to the left or to the right, according 
to the Falcon guide Turn and Burn 
(Compule! Books, $14.95). The land- 



ing gear must be down, as well, but 
you knew that.

loo, you can decide his Fate. 

Waterloo is unique in sev- 
eral respects. It is the first war 
game in which each player (up 
to two are allowed) not only 
takes on the role of a general, 
but also views the battlefield 
through his eyes, as opposed 
to seeing an unrealistic "god's- 
eye view" of the entire land- 
scape. Secondly, you can't con- 
trol your units' actions; 
instead, you give up to eight 
orders per turn to your corps 
commanders by typing in- 
structions (for example, 
"Lobau shell Mont St. Jean for 
three hours"). The command- 
ers then follow the orders to 
the best of their abilities. The 
view becomes even more real- 
istic as "fog-of-war" conditions 
settle in: A commander can 
see only what is within his 
range of vision, and can gain 
further information on the ac- 
tion only from sporadic and 



possibly unreliable battle re- 
ports. Units are identified by 
clicking on tbem. 

The game's graphics are 
also different. Standard mili- 
tary symbols and toy-like icons 
have been replaced by multi- 
colored rectangles and squares 
that depict units just as they 
would appear in real-life from 
a distance. The program re- 
draws the screen whenever 
units move or a player's view 
changes. Sound is absent, but 
unnecessary; this is a thinking 
person's game. 

The game's rules are easy to 
understand, and setup is even 
easier, but there's still room 
for improvement. Only the 
Waterloo battle is available. I 
would have prefered to re-cre- 
ate the two earlier battles as 
well, and to have been able to 
modify the expertise of the 
troops and their commanders. 
Judging distances is also diffi-

cult, even with the map pro-

long orders will take to reach 
a unit and be carried out is a 
matter of experimentation.

Nuclear War 

By Graham Kinsey 

I F YOU FEEL you can laugh at 
war after the recent political 
changes, then Nuclear War will 
give you a good chuckle. As 
president of a member nation of 
the exclusive "nuclear club," you 
do battle with four powerful, 
computer-controlled world 



one of three options. First, 
you can order your people to 
produce nuclear bombs, mis- 
siles, bombers, or nuclear de- 
fense systems (the program 
decides randomly which are 
produced). Second, if you feel 
peaceful but devious, you can

leaders (including Ronnie Rav- 
gun, Ayatollah Kookamamie, 
Ghanji, and Tricky Dick). Each 
player starts with five well-popu- 
lated cities that create the toys of 
nuclear destruction on com- 
mand. These cities and their 
populations are the keys to suc- 
cess, for the number of people in 
your country (or empire) deter- 
mines how many nuclear items 
can be produced in one turn. 
(Lose your total population, of 
course, and you lose the game.) 
In each turn, you choose 



assault a foreign city with 
propaganda in hopes that a 
few million inhabitants will 
move to your country. Finally, 
you can push The Button, and 
ruin an opponent's weekend! 
You can transport a bomb to 
its target via a missile, which is 
a one-way trip, or via bomber, 
which can carry multiple pay- 
loads and is less vulnerable to 
defense systems. 

To communicate your inten- 
tions (or lies) to your oppo- 
nents, Nuclear War offers the»-

Day of the Viper 

By John Ryan 

I AM INHERENTLY suspi- 
cious of Amiga software that 
sports IBM screen shots on 
the package. Happily, my sus- 
picions were ill-founded with 
Day of the Viper. This gem is 
100% Amiga, with all the 
color, stereo sound, and high- 
speed graphic action that con- 
noisseurs expect. 

The premise of this science- 
fiction adventure is simple: 
The year is 2782, and the evil 
cyborg GAR has entrenched 
himself in the last defense in- 
stallation left to humankind. 
The compound comprises five 
buildings, each containing five 
progressively difficult levels 



E S E R V E 

caused by the Heinous Heifers. 
Nuclear War's graphics and 
sound are good, as is its com- 
patibility. The game will run 
on accelerated Amigas, allow 
multitasking, and install on a 
hard drive. While Nuclear 
War is not for those who can't 
take a nuclear joke, I found it 
hilarious. ($49.95 New World

filled with traps, robot assas- 
sins, and other nasties. Your 
task is to guide the Viper-5 ro- 
bot through the maze of hall- 
ways in search of tools to 
destroy GAR and his alumi- 
num-headed minions. 

A beautifully detailed screen 
depicts both a three-dimen- 
sional, first-person view of the 
surroundings and an overhead 
view— courtesy of automap- 
ping. The program not only 
details where you've been, but 
also what you've found there. 
You can pick up, drop, or oth- 
erwise manipulate items in 
various ways, and an elec- 
tronic notepad automatically

records their whereabouts. 

The meat of this mouse-con- 
trolled game is the chase. 
While your robot is searching 
the defense complex, GAR and 
his gang are out to ruin your 
day. You must clear out the 
enemy robots from each build- 
ing level and fend off attacks 
from several directions at 
once. Each of the 30 or so ro- 
bot variations has its own pe- 
culiar weaknesses. Only by 
targeting these weak spots and 
exploiting the various weapons 
you find, do you keep your 
sprockets firmly in place. 
Weapons selection, energy 



management, and knowing 
when and where to fight are 
the keys. 

Getting started with Viper is 
easy. The game is copy-pro- 
tected by password and installs 
easily on a hard drive. More- 
over, the short and informative 
instructions are geared toward 
getting you quickly into the 
game without a lot of fuss. Day 
of the Viper offers hours of 
mouse-pounding fun, and no 
two games are ever alike.

Risk 

By Graham Kinsey 

SHIFTING THE ACTION 
from the tabletop to the screen, 
the Amiga version of Risk re- 
tains the original's rules and 
adds lots of new options. You 
battle up to five human or 
computer opponents and can 
specify three skill levels for 
computer foes. (The comput- 
er's Easy setting isn't really easy 
at all, as it makes the computer 
a very reckless and therefore 
dangerous opponent.) 

You can play four varieties 
of games: the standard short 
and long U.S. formats or the 
short and long British var- 
iants. The British versions are 
very different, with automatic 
territory selection at the begin- 
ning of the game and a flat 
card-exchange rate. In the 
short UK version, each player 
has a mission, such as wiping 
out another player or con- 
quering specific continents. 

If you'd rather, you can cre- 
ate your own variation by 
combining features from the 
four versions or choosing from 
the multitude of options. For 
example, you can specify a low 
exchange rate for the US 
games, supply lines (where 



you can shuffle armies around 
almost at will), and a limit on 
the number of armies in one 
territory. There are also some 
options to speed up play, in- 
cluding the ability to disable 
the scrolling effect and the 
Continuous and Do-or-Die at- 
tack modes. 

While all these choices make 
the game seem great at first, it 
has many very annoying prob- 
lems. For starters, Risk cannot 
be installed on a hard drive 
and does not allow multitask- 
ing. (At least it does work with 
accelerated Amigas.) Also, 
there is no reason why the en- 
tire Risk board can't fit en- 
tirely in one screen; in the 
public-domain Risk clone, 
Jeopard, it does so nicely. The 
color options are pathetic, and 
the only nice thing I can say 
about the sound effects is that 
you can turn them off. While I 
liked Risk as far as the options 
went, it falls short compared 
to a well-written Amiga war- 
strategy game such as Empire.

from p. 16 

unless you use ZapPort on a copy of the 
AUX-handler file in the L: directory of 
the Workbench and create your own 
mountlist entry for the altered copy. 

Instead of using operating-system rou- 
tines to speak to the serial port, most 
MIDI programs send data directly to the 
hardware. This means that for the most 
part, music-sequencing software must 
support the Serial Solution directly in or- 
der to use it as another MIDI port. So far, 
the only program to provide such support 
is Blue Ribbon Bakery's Bars & Pipes 
(a demo copy of which is included on the 
Serial Solution disk). Bars & Pipes uses 
the Serial Solution to add 16 MIDI chan- 
nels to the Amiga's standard 16, making 
it the first Amiga MIDI program to con- 
trol up to 32 channels at once. 

Checkpoint is also working to add 
compatibility with programs like Music-X 
(Microlllusions) and the Dr. T's line of 
music software. Because the board has 
only one 25-pin connector, it can plug 
into just a single MIDI adapter. Given 
sufficient demand, however, Checkpoint 
may supply an adapter for the 9-pin 



connector, so that you could add another 
16 MIDI channels, for a total of 48. 

Get It On 

Although installation of the driver soft- 
ware may sound complicated, Check- 
point has made it as painless as possible. 
The supplied software contains an auto- 
mated installation script that transfers 
the Exec-level driver to the Expansion 
drawer of your Workbench disk, moves 
the AmigaDOS handler to I: directory, 
adds entries for SER2: and SER3: to the 
devs: Mountlist file, and plugs commands 
into your startup-sequence to mount 
these devices. 

For those unfamiliar with editing an 
icons Tools Types, there is a TSSPref 
program that lets you set serial-port 
preferences and automatically change 
the Tool Types in the driver icon. Its in- 
terface is very similar to the serial screen 
of the AmigaDOS Preferences program. 
Those wishing to install the software 
manually will appreciate the fact that the 
documentation explains this in great de- 
tail, even including a checklist. 

The Serial Solution provides an inex- 



pensive way to add serial ports to your 
Amiga 2000 or 3000. It meets the needs 
of those who wish to use several serial 
peripherals al once and of those wanting 
to run serial applications with higher 
speeds than the standard Amiga port can 
reliably support. In addition, its excep- 
tional MIDI support makes it the board 
of choice for musicians who need more 
MIDI channels.

A look inside Master Sound's case reveals 
mostly empty space. 



Uses an AD7576 analog to digital converter (a cheaper version of Ihe 
chip used in Perfect Sound). The AD 7576's lack ol track and hold 
reduces Master Sound's sample accuracy. 



No method of adjusting input gain with the sampler. This makes it 
difficult to sample from the line outs of CD players, tuners, etc. 



One mini plug for line level mono sampling. To sample from common 
RCA jacks you will have to buy an adaptor. No way to sample in stereo.

REVIEWS 



Sound is the lowest priced eight-bit audio 
digitizer on the Amiga market today. It 
captures and plays back high-quality sam- 
ples, but whether it is a bargain depends 
on how easy it is to use and how useful 
the resulting samples are. (To compare 
Master Sound with other digitizers, see 
"Sizzling Sounds," Oct '89, p. 48.) 

Master Sound consists of a small car- 
tridge and a disk of non-copy-protected 
software. The hardware fits snugly into 
your Amiga's parallel port and has just 
one mono mini-plug (3.5 mm) for input. 
To hook it up to your audio device, you 
will probably need either an adapter or a 
special cable (not many audio devices 
use mini plugs for output), both of 
which add noise to the input signal. An- 
other severe design deficiency is the lack 
of gain control on either the hardware 
or software. As a result, you must adjust 
gain through the audio source or 
through an external mixer, adding in- 
convenience and, in the latter case, ex- 
pense as well. 

The Master Sound program is rela- 
tively small and sports a nice-looking 
control screen with embossed-style but- 
tons. The top third of the screen shows 
an approximation of the sample's wave- 
form, once it is in memory. Below this 
are sample playback and location but- 
tons, styled as on a tape recorder. An 
oscilloscope in the bottom-right corner 
should facilitate setting input levels, but 
in my tests the scope was only moder- 
ately accurate. On the bottom-left side 
are editing controls. Two numerical dis- 
plays show the cursor location within the 
sample, and another smaller readout 
gives the sampling/playback rate. 

Recording samples is fairly straightfor- 
ward. Once you have judged the input 
level to be adequate by monitoring the 
oscilloscope and the speaker, you set the 
sample level— this is difficult to do with 
any precision— and click the record but- 
ton twice. (Clicking a third time stops 
the recording.) You can also set the pro- 
gram to begin recording automatically 
once the sound reaches a preset level. 

The sample rate can be as high as 59.6 
KHz, which makes for extremely clean 
and detailed, though large, sound files. 
Sounds sampled at very high rates are 
unusable in programs that limit the rate 
to 28 KHz, but Master Sound lets you 
compress samples by 50% and adjust the 
playback rate. Because the controls are 




The Master control screen. 

so coarse, however, doing so is difficult. 
There is no resampling feature. 

Stormy Weather 

A sampler without editing features is like 
a day without sunshine, and the sun 
doesn't shine too brightly on Master 
Sound. Although the standard editing 
features are implemented (you can mark 
and magnify sample sections, cut, paste, 
overlay, and apply filtering and volume 
changes), the design hinders smooth op- 
eration. The sample display is very 
coarse, which makes it difficult to zero in 
on editing and looping points. 

There is also no undo option, which, 
coupled with die fact that the controls do 
not provide leveling (you get your choice 
onlv of on or off), makes sample editing 
a hit-or-miss process. Filtering and Vol- 
ume Change, for example, operate with 
a set level, and there is no recourse for a 
mistake or change of mind. The Overlay 
effect lets you cut a piece out of a sample 
and paste it over something else, but 1 
found it almost impossible to blend the 
level of the pasted section with that of 
the destination. 

Master Sound has a sequencer of 
sorts: Using it involves pasting all the 
sounds you want to use into one master 
sample and assigning each part to a key 
on the numeric keypad. You can record 
into each of the Amiga's four sound 
channels using these keys. The demo se- 
quence on the program disk, produced 
in this way, hints at some interesting 
possibilities. Unfortunately, I was unable 
to get this feature to work, in part be- 
cause I could not follow the very confus- 
ing instrucdons in the manual. 

The manual needs a major overhaul. 
It is skimpy and vague in every section, 



but because the software has no pull- 
down menus or help feature, you must 
depend on it to explain what each icon 
and button does. Even those familiar 
with sampling will find the manual inad- 
equate, and for beginners it will be 
hopelessly confusing. For example, the 
rather basic bit of information that there 
is no button to exit the program is not 
mentioned until almost the end of the 
manual, and then only in passing. (The 
key combination required to quit is bur- 
ied in a section describing how to make 
a demo.) 

I cannot recommend Master Sound for 
any purpose other than the very limited 
one of producing reasonably good sam- 
ples. Editing requires a separate sample 
editor such as AudioMaster II (Oxxi/Ae- 
gis), which also does a good job of control- 
ling the hardware. I have to wonder what 
market niche Microdeal had in mind for 
Master Sound. Its low price makes it at- 
tractive to beginners, but the manual 
rules it out for that segment. There are a 
number of better 8-bit samplers on the 
market; 1 wish the developers had put 
their talents and time to work on a prod- 
uct we didn't already have.

Text-adventure creation on the 
lighter side 

By Dean Friedman 

WITH THE RECENT explosion of ex- 
citing authoring systems for the Amiga, 
would-be programmers finally have al- 
ternatives to text-intensive languages. In 
facilitating the manipulation of graphics, 
animation, and audio, however, most 
icon-based authoring systems have, to 
varying degrees, neglected the more 
mundane job of handling text. For those 
weaned on text-adventure games like 
Zork (Infocom), nothing gets the blood *

REVIEWS 



flowing like a powerful word parser that 
interprets conversational keyboard input. 
Sometimes the only reasonable course of 
action in an adventure is to see what 
happens if you have your hero "stick 
fork in monster's eye." 

T.A.C.L., The Adventure Construction 
Language, is a script-based game-author- 
ing system designed specifically to han- 
dle the kinds of logic and language that 
are characteristic of text adventures. It 
allows you to display IFF and HAM 
graphics files and includes a simple util- 
ity for generating audio tones across the 
chromatic scale. It even provides a 
graphic editor, called VGED (Vector 
Graphic Editor), with modest paint tools. 
These enable you to create non-IFF 
graphics, which take up considerably less 
room on your disk than IFF files. 

T.A.C.L. employs a BASIC-like script- 
ing language that anyone with even min- 
imal exposure to BASIC ought to be able 
to use after carefully examining the 
demo scripts included with the program. 
Even novices should be able to find their 
way around with some patience and per- 
severance (although the job would be 
easier if the manual were less verbose 
and better organized). 

Flex Files 

What gives TA.C.L. its muscle is its 
game template, which consists of five file 
categories (Adventure, Room, Object, 
Subroutine, and Vocabulary) that define 
separate portions of the game's universe. 
Following established adventure-game 
convention, TA.C.L. provides a format 
in which the hero moves from one loca- 
tion to another by responding to direc- 
tion commands (North, East, West, 
South), collects objects, confronts charac- 
ters, and acts or is acted upon. Once you 
have planned out gameplay on paper, 
you can simply plug the various game 
elements into the appropriate files. 

Creating the Room file involves defin- 
ing a series of adjacent rooms and then 
describing the consequences of entering 
them. Default statements define a room's 
entrance(s) and exit(s) and provide the 
means for linking rooms together. Com- 
mands are typed in capital letters, while 
values and variables are not. Descriptive 
comments, which the program does not 
act upon, are preceded by an asterisk. 
Any text you wish displayed during the 
gameplay must be preceded by the letter 




T. (Using the Amiga's Say facility, you 
can opt to have the computer verbalize 
text as it is displayed.) 

The Object file, which defines not only 
inanimate objects, but also characters, is 
created in much the same way. You type 
in the name of the object or character 
and any synonyms or accompanying ad- 
jectives. For example, you could enable 
the program to distinguish between the 
silver key and the gold key, or have it 
understand that light and lamp are one 
and the same. You can assign attributes 
or variables to objects (the lamp can be 
on or off), and you can script events to 
occur according to the state of those at- 
tributes. An object's definition also in- 
cludes an action (such as open, drop, or 
throw) and you can link events to occur 
once that action is executed. 



YOUR TURN! 



TA.C.L. is fun to play around with and 
easy to pick up if you know program- 
ming. The manual is not terribly good, 
though, for nonprogrammers. The in- 
terpreter won't wrap text from line to 
line as a word processor does; it's a 
pain to realign when editing. I would 
appreciate an editor that could gener- 
ate most of the code for you. T.A.C.L. 
has no interface; it's really just a lan- 
guage and compiler. It is very flexible, 
however, and you can use it in lots of 
different ways. 

Matt Ritchie 
Austin, TX 



The Subroutine file provides a means 
for creating modules (subroutines) for 
common blocks of script, which can be 
summoned by a Call subroutine from 
another file. The Vocabulary file is where 
you define responses to actions that are 
not necessarily attached to a specific ob- 
ject. Here is where you can have some 
fun anticipating the varied commands of 
the players and responding to them 
humorously. 

The Room, Object, Subroutine, and 
Vocabulary files are all organized and re- 
ferred to by the main, or Adventure, file. 
The Adventure file contains the names of 
all other files as well as variables that af- 
fect the overall game (whether it it day- 
lime or night, for instance), and any 



password you may require of the player 
as a type of copy protection. 

You can attach graphics and sounds to 
either rooms or objects, and choose 
whether they are to be displayed or 
played before or after command entries. 
While the graphics editor is modest but 
functional, audio implementation is de- 
cidedly weak. TA.C.L. supports IFF 
graphics files, but not IFF audio files. 

Once you have created your five files, 
TA.C.L. compiles them into compact 
code and automatically generates the 
logic routines that keep track of where 
your player is, what he sees, which ob- 
jects he possesses, and what conditions 
he encounters upon taking specific ac- 
tions — all according to the elements you 
have scripted. Simply put, you decide 
what is to occur during the course of the 
gameplay, and TA.C.L. makes it 
happen. 

You can test your game from within 
the PADV (Play ADVenture) module, 
which offers many options, including 
toggling between various images and 
whether you hear audio playback and 
speech. The PADV player module is 
freely distributable, so any games you 
create with TA.C.L. can be marketed 
commercially. 

A Better Program 

What TA.C.L. does, it does well. By 
dividing the game universe into five dis- 
tinct files and automatically incorporat- 
ing those files into a template, TA.C.L. 
drastically reduces the amount of organi- 
zing and programming involved in cre- 
ating games from scratch. I wish, 
however, that it could handle AN I Ms in 
addition to IFF images, however, and 
that it handled IFF audio files. Better yet 
would be an ability to trigger SMUS 
files, so that games could include poly- 
phonic music sequences. 

I would also like to see text input and 
response on the same screen as the im- 
ages. At present, text is shown on a sepa- 
rate screen, so the player never gets to 
view a picture while typing commands. 
Finally, I would like a simpler program 
interface with more graphic elements. 

T.AC.L. goes a long way toward mini- 
mizing tedious and mundane program- 
ming chores, but it seems that even more 
tasks could be automated. It is true that 
an adventure game's elegance and com- 
plexity is determined by a logical series of »

Aztec C 5.0a 

One more time! 

By David T. McClellan 

MANX'S AZTEC C compilers have been 
around for a long time on a number of 
computer platforms. Amiga version 5.0a 
comes with a thick paperback manual and 
live disks. An install procedure on the first 
disk installs the software on two floppy 
disks or a hard disk. (Single-floppy sys- 
tems are not recommended for running 
the compiler.) In addition to copying 
disks, the install program is able to do 
some useful tailoring: The compiler can 
generate several code and data models 
(from small to large, a la IBM PCs), and 
four separate floating-point models 
(Amiga IEEE, Motorola 68881, Amiga 
FFP, and Manx IEEE). 

t )ue complaint is lhal you musl boot 
from one of the installed disks. I'd like to 
see an install procedure that adds to 
your startup-sequence and allows you to 
edit the results. In order to use the com- 
piler and also my own startup scripts, I 
had to transfer the Manx files to my boot 
disk by hand — not a time-consuming 
process; just inconvenient. 

You Could Use Some Z 
There is one tool in this package you 
may end up using more frequently than 
the C compiler itself: the full-screen edi- 
tor, z. Nearly a clone of the Unix vi edi- 
tor, it has honks to the compiler for 
error fixing. The QnikFix compiler op- 
tion lets the compiler invoke the editor 



and step you through the source-fixing 
errors as it finds them. It then automati- 
cally recompiles when you exit. Z didn't 
crash on me (as have some Modula-2 
compiler/editors that tried the compile/ 
edit trick), and it makes syntax fixing 
quick. 

The compiler sports a number of 
other options-CCOPTS, CCTEMP, IN- 
CLUDE, and CCEDIT— that you can 
pass in as command-line switches and 
provide via Manx-environment variables. 
Manx variables are not normal Amiga- 
environment variables; you must set 
them — preferably in your startup or init- 
for-aztec script— with Manx's own Set 
command instead of AmigaDOS's Set- 
Env. Various switches, similar to those 
provided by Lattice and Unix Portable 
C, control the code, data and math 
models, various optimizations, prepro- 
cessing, and debugging. 

The 5.0a compiler supports ANSI C 
conventions, including two extra 
switches: "-k" for Kernighan & Ritchie C 
rules, and "-3" for code written using 
earlier Aztec C versions (3.6 in particu- 
lar). My only complaint about the com- 
piler is that you can compile only one 
file at a time on the command line. (If 
you use the Make utility, this is no big 
deal, but for compiling several files by 
hand, this setup requires extra time.) 

The compiling process has two visible 
passes: The compiler itself generates 
assembly language and passes it to the 
assembler (which you can also use sepa- 
rately). The assembler generates the .o 
object files that go to Manx's linker. This 
process is reasonably fast, and the com- 
piler generates good code. 

You invoke the linker separately, pass- 
ing it the .o files and the libraries you 
want. It finds the libraries using the 
CLIB Manx-environment variable, and 
generates a normal AmigaDOS execut- 
able. It also handles segmented (overlay) 
linkages, and you can choose to include 
information for the debugger in the 
executable. 

Aztec 5.0a provides three debuggers, a 
librarian, a couple of object-file and exe- 
cutable-file dissectors, text-file archivers 
and comparators, and some Unix-like di- 
rectory utilities. A Make tool uses your 
text databases (makefiles) of source-file/ 
object-file dependency relationships and 
rebuild rules to keep your programs up 
to date. By using the dependency rules 



and checking last-modified dates for 
source-file changes. Make recreates exe- 
cutables, recompiling and relinking only 
when necessary. This tool keeps the edit/ 
compile/link/test cycle simple by doing 
the bookkeeping and rebuilding for you; 
you just edit and test. 

The three debuggers (one for assem- 
bly language and two C source-level de- 
buggers that support different math 
libraries) are good. SDB, the source-level 
debugger, provides the usual functions: 
setting and clearing breakpoints, doing 
stack tracebacks, examining and setting 
C variables and memory in several ways, 
displaying C source, setting chunks of 
memory to new values, and disassem- 
bling object code. 

Breakpoints can be unconditional or 
conditional (for example, "break if sales 
< 15"). You can attach debugger com- 
mands to the breakpoints, single-step 
through the source, and examine vari- 
ables at different stack levels (including 
separate frames of a recursive routine) as 
bytes of memory or as C-data structures. 
An especially handy feature is the ability 
to create debugger macros. SDB looks at 
least as robust as the other Amiga C and 
Modula-2 debuggers I've worked with. 

Manx's C library supports not only all 
AmigaDOS and ROM Kernel functions, 
but also most Unix 5 studio, string, 
memory, math, error-handling (setjmp/ 
longjmp), and miscellaneous functions, 
plus a few Aztec-specific ones for slack 
checking, CLI calls, and such. Their in- 
cluded directory also has function proto- 
types for all of these, so you can take 
advantage of the ANSI C argument type- 
checking and type-promoting features. I 
ported over several programs I'd done 
in Lattice 5.0, using the 32-bit integer 
compilation option, and they all worked 
fine. Manx supplies a few example files 
(display hacks and others) for those new 
to C on the Amiga. 

Manual Transmission 

The manual describes all the tools, options, 
and supported ANSI C features, and it pro- 
vides briefs of the library features, includ- 
ing a handy listing of prototypes for all 
.Amiga ROM Kernel functions. I found a 
number of minor typographical errors, 
particularly in the /. editor examples, but 
none are crippling. Documentation on the 
debugger is sparse in places; several power- 
ful commands are covered only briefly. In- ►

dexes are scattered over several major 
sections— there's one for the compiler and 
related tools, one for the libraries, and one 
for the Uni-Tools (make, z, and so on), and 
another for the debugger. I needed an in- 
dex just for the indexes! 

Overall, I like the package. Although 
the manual needs help, the ANSI C sup- 
port, the depth of the C libraries, and 
the symbolic debugger are good, and the 
other tools are useful. Aztec C's main 
competitor, Lattice C, also provides 
ANSI C compatibility, good libraries, and 
a very good symbolic debugger. Both 
compilers generate decent code. Aztec C 
provides a 1 6-bit integer-compiler option 
that can win some cycles— but so can 
careful coding, using shorts and longs 
where appropriate. 

Manx's Macintosh compiler suppos- 
edly supports the same C language as its 
Amiga version, whereas Lattice is more 
into the PC market. If you are writing 
programs for more than one hardware 
market, this will determine your choice. 
If you've already got Lattice 5.0, don't 
change. But if" you have Aztec C 3.46 or 
no compiler at all, 5.0a may be a good 
choice for you.

ALF2 

SupraDrive with 
WordSync 

More drive options. 

By Harv Laser 

HARD-DRIVE CONTROLLERS come in 

many flavors. My ever-increasing appe- 
tite for storage space recently led me to 
sample a couple of them, namely ALF2 
from Pre'spect Technics and Supra's 
SupraDrive with WordSync. 

Modular Control 

The ALF2 (Amiga Loads Faster) control- 



ler consists of a base auto-configuring 
A2000 card (onto which you can mount 
a 3.5-inch hard drive) with a module to 
implement the controller function for 
any of various hard-drive types: ST-412 
or -506, SCSI, ESDI, and AT. (An exter- 
nal box SCSI connector is available.) 
While only one module can be used per 
card, the ALF2 software allows for multi- 
ple cards. This modular concept makes 
ALF2 thicker than the average board, 
but allows for great versatility. Lnfortu- 
nately, you do not have the option of us- 
ing power from the card for the hard 
drive. 

Included with the installation software 
are partitioning, partition password-pro- 
tection, hard-drive auto-parking, drive- 
backup, and disk-performance pro- 
grams. The partition password protec- 
tion can extend to storing the Rigid Disk 
Block (RDB) autobooting information on 
floppy, then deleting the RDB partition 
information from the hard drive, thus 
virtually assuring complete security and 
protection from viruses. Although such 
niceties are available in the public do- 
main, I w-as pleased to find them in- 
cluded on the installation disk. The 
software supports both XT and AT 
Bridgeboards as well as autobooting 
IBM virtual drives. 

ALF controllers come in a variety of 
models for the A500, A1000, and A2000- 
series machines. I tested two A2000 con- 
trollers of the autobooting variety— 
ALF2-SCSI and ALF2-RLL-affixing 
them with various hard drives. (The 
hardware comes without cables.) The 
boards themselves appear to be of good 
quality, with no jumpers or cuts 
apparent. 

All controller modules employ the 
same software, which is evidence of its 
versatility. The software can format a 
hard disk using an error-map list that 
you enter, and it can then check the disk 
for additional errors. You can add any 
errors discovered to the bad-block list 
and remove them entirely from access by 
normal DOS operations, which may 
prove especially helpful with older 
drives. 

The software works well, and I found 
just one glitch: The keymap is not USA1 
(or any other USA format), and USA1 
does not appear on the disk. This is a 
minor quibble, however, as you can 
make it through a normal installation 



with no problem. 

On startup, the installation software 
checks to see which controller is present 
and then boots to the Workbench. You 
simply click open the ALF2 disk icon, 
open the ALF2 -Install drawer, and click 
the InstallALF icon. From there, installa- 
tion is automatic. 

And a One and a Two 

The ALF2 SCSI controller— versatile and 
easy to use— is a good performer, as the 
comparative data shows. (See Table 1 
for DiskSpeed results.) 1 performed 
some tests on a nine-meg 36MHz-030- 
equipped A2000 with a 340MB Micro- 
polis drive, a 80MB Quantum drive, 
Micro Way's flickerFixer, and an Interac- 
tive Video TrumpCard; others were run 
on standard 1-meg (chip RAM) A2000s. 
The ALF2 SCSI controller worked per- 
fectly on Revision 4. 1 and Revision 4.4 
A2000 motherboards, but would not get 
past the white boot-up screen on two Re- 
vision 6.2 motherboards. 

The ST4 12/506 RLL-style autobooting 
ALF2 controller is one of the few Amiga 
controllers that supports the common 
(read: "cheap ") IBM-standard hard 
drives. (Commodore's A2090A also sup- 
ports this type of drive, but only in the 
low-capacity — and usually slower — MFM 
format.) Because the ALF2 ST412/506 
controller module supports the RLL en- 
coding format and uses fast OMTI chips, 
it clearly out-performs the old A2090A, is 
not plagued by overscan problems, and 
can boot from an FFS partition. As with 
the ALF2 SCSI controller, this unit 
works on Revision 4.1 and Revision 4.4 
Amiga motherboards, but fails on my 
two 6,2 motherboards. 

The sometimes-confusing ALF2 man- 
ual contains a table of contents, a glos- 
sary, and several appendices, but no 
index. Even so, step-by-step instructions 
complement the automatic-installation 
software and all utilities on the ALF2 Ex- 
tras disk. The appendices contain infor- 
mation on controller pinouts, drive 
types, ST-412, -506, and SCSI interfaces, 
and a useful section on third-party soft- 
ware installation on common hard-drive 
configurations. 

I was disappointed, however, to find 
that the manual refers you to the docu- 
mentation that comes with your hard 
drive for information on mounting the 
drive. I think the ALF2 manual should 



86 August 1990 



REVIEWS 



describe the basic connections of the 
power, data, and LED-indicator cables. 
Along similar lines, hardware docs for 
the ALF2 base card and each module 
should list all jumper locations and func- 
tions with default settings, to help you 
avoid problems and diagnose any that 
do occur. 

One feature of the software is a poten- 
tial source of problems. When the system 
is set up without an accelerator card, the 
ALF2 software recognizes this and modi- 
fies itself accordingly for greater per- 
formance. If you install an accelerator 



later, you may find that the system no 
longer boots. To correct this problem, 
simply disable the accelerator card and 
use ALFPrefs to rewrite the hard drive's 
RDB booting information for an acceler- 
ated system. 

Supra-ize! 

Like the ALF controllers, SupraDrive 
with WordSync comes in a variety of 
configurations for all Amiga models. You 
can buy it without a drive attached (as 
the ALF units come, for SI 99.95) or 
with. The SupraDrive unit I tested came 



with a Quantum 40s 3.5-inch drive 
mounted and wired to its half-card rails. 

This hardcard is virtually idiot proof. 
Supra's documentation (a 90-page well- 
indexed manual and some additional 
stapled sheets) and the two accompany- 
ing floppy disks are skillfully assembled 
and quite complete. Virtually nothing is 
left to guessing— a good thing where 
hard drives are concerned. The card as- 
sembly appears to be of high quality, 
with no hanging wires or sloppy 
soldering. 

Installation is simplicity itself. I *-

opened my A2500 (with 6,2a mother- 
board), pushed the hardcard into an 
empty Amiga slot, and closed it up 
again. Because my 2500 came equipped 
with Commodore's A2090A autobooting 
controller and a Rodime 40MB ST-506 
drive, I chose to disable WordSvnc's 
autobooting feature. This is a trivial task 
that involves moving one small jumper, 
thoughtfully located at the top of the 
card so that moving it again does not re- 
quire removing the card from its slot. As 
with other hardcards, installing the Word- 
Sync in any slot other than the one near- 
est the power supply renders the slot to 
its right unusable (because of the width 
of the drive). 

Although the manual's text and illus- 
trations indicate that the drive requires a 
power connection from the Amiga, this is 
not the case. This card takes power di- 
rectly from the slot into which you install 
it. This was the only major discrepancy I 
noted in the manual. 

As with other Supra drives, this one 
uses the proprietary SupraMount com- 
mand in place of a mountlist entry in the 
DEVS: directory. This simplifies matters 



further, as it frees you from the vexing 
chore of writing or editing mountlists. 
Booting off the Supra installation disk 
sets up the drive and runs SupraFormat, 
a very intuitive program that displays 
your hardcard partitions and lets you 
change or modify' them easily. Supra- 
Mount supports up to 30 partitions per 
drive. I chose to leave the drive in its de- 
fault factory configuration: two 20-meg 
partitions. You can format the entire 
drive, including the autoboot partition, 
with the FastFileSystem. 

For expert users, Supra provides a 
program called SupraEdit, which lets 
you change low-level system information 
(the same data that would be stored in a 
mountlist entry— partition flats, boot 
priority, buffer sizes and types, and so 
on) for each drive partition. The manual 
warns you to stay away from SupraEdit 
"unless you absolutely know what you 
are doing." Good advice. 

A drive-parking utility, the CLImate 
"dirutil" program, and other programs 
and icon-driven scripts round out the 
plethora of software included. Supra fre- 
quently adds to this software, providing 



updates by mail for a nominal fee, and 
for free on national electronic networks. 

WordSync is Supra's own drive-access- 
ing scheme devised to replace the com- 
mon DMA (Direct Memory Access) 
method some other controllers use. I'm 
impressed by how well Supra's Word- 
Sync strategy meets the company's claims 
(see the DiskSpeed test results in Table 
1). The WordSync hardcard is not the 
fastest setup on the market, but it's easily 
twice as fast as my 2090A- Rodime pair. I 
noticed none of the typical DMA slow- 
downs when talking to the WordSync 
drive while downloading at high speed, 
or when using DeluxePaint III (Elec- 
tronic Arts) in full overscan. 

The 40MB WordSync card-and-drive 
combo is well built, relatively fast, and as 
close to a turnkey system as I have seen. 
When sold by itself, the card is packaged 
along with the same excellent manual 
the hardcard system supplies. 

Hard Bargain? 

The Supra units beat out the ALF2 cards 
in the professional presentation depart- 
ment, but we were able to get better

Which Ware? 

Your article "The Great Software 
Weigh-in" (Apr '90, p. 24) lists the 
program "QED" as being in the pub- 
lic domain. It is not. QED is freely 
distributable shareware; copyright is 
claimed and owned by me. In return 
for a S20 registration fee, I send doc- 
umentation and a current program 
version. The program is now being 
enhanced and will likely be sold com- 
mercially in its final form. I believe 
that at least two other programs men- 
tioned in that article— J R Comm and 
Access 1.3— are also incorrectly la- 
beled as PD. 

—Darren M. Greenwald 
Santa Anna, CA 92704 

In "The Great Software Weigh-in," I 
incorrectly identified QED, JR Comm, and 
Access 1.3 as public domain. When refer- 
ring to software that can legally he shared 



without cost, I, like many people, sometimes 
inaccurately substitute the term "public do- 
main" for "freely distributable." PD pro- 
grams are freely distributable software tliai 
an author has fully released. Shareware is 
also freely distributable, but in this case, 
while the author may release distribution 
rights fully or partially, he does not relin- 
quish ownership.

In the article "Cutting the Red 
Tape" (p. 42 in the 1990 Video and 
Animation Special Issue), Geoffrey 
Williams states that ED-Beta , S-VHS, 
and Hi8 VCRs "offer twice as many 
scan lines (or more), which signifi- 
cantly improves the picture resolu- 
tion. . ." Whoa there! The only time 
you will find more or less than 525 
scan lines is in a non-standard com- *-

puter display or in some foreign tele- 
vision standard such as PAL or 
SECAM. Ail recordable video in this 
country has 525 scan lines (that's the 
NTSC standard). Even the true com- 
ponent formats (M-ll and Betacam) 
and the so-called Y/C component for- 
mats (such as S-VHS and ED-Beta) 
use the NTSC signal system. These 
components can record more hori- 
zontal resolution than NTSC, but 
since horizontal resolution is ex- 
pressed as a measurement of vertical 
iines, there is no connection with scan 
lines, which are horizontal. 

The same article says that a "re- 
corder should have at least four re- 
cording heads; fewer than that will 
not stand a chance of cleanly record- 
ing Amiga graphics." I've successfully 
recorded Amiga graphics onto 5 /.,-inch 
and S-VHS, which both sport two re- 
cording heads, and know of no VTR 
with more than that. 

Finally, the caption "a Time-Base 
controller" accompanying the photo 
of a production switcher and two 
FOR.A TBCs could cause confusion

n u 



for the uninitiated. 



-Joe Henry Morin 

Jasper, AR 



While it is true that the number of scan 
lines remains constant in an NTSC signal, 
the ability to resolve them does not. Techni- 
cally, high- and medium-resolution pic- 
tures have the same number of scan lines, 
but for all practical purposes, medium-res 
can resolve only half of them. It would be 
more accurate to say that the Y/C compo- 
nent formats offer higher horizontal reso- 
lution, making better use of the available 
scan lines, but the bottom line is that you 
gel a much better picture. 

The term "video heads" should read 
"recording Iteads"; I hope this did not con- 
fuse too many. I agree that the picture 
could have been cropped more carefully to 
show just the TBC, and the caption should 
refer to it as a Time-Base Corrector.

Mind My Business 

WITH THE SHELL'S More command 
and a text file, I developed an inexpen- 
sive substitute for a calendar/reminder 
program. With a text editor, I created a 
short ASCII file of important dates and 
reminders of things I have to do. I then 
saved the file to my Workbench's T di- 
rectory under the name of Notes. Fi- 
nally, I used a text editor to add the 
following line between the LOADWB and 
ENDCLI >NIL: commands in my 
startup-sequence: 

DFO:Utilities/More DFO:t/Notes 

Now, whenever I start or reboot my 
Amiga, the first page of the Notes file au- 
tomatically appears on the screen. Press- 
ing the space bar displays the next page, 
if there is one, or closes the file.

Get a Little Nearer 

FOR THOSE READERS who still use an 
old Epson printer that lacks an NLQ 
(Near Letter Quality) mode, here is a 
way to get an almost-NLQ printout. 
You'll need to use Workbench 1.3 and 
the epsonxold primer driver. (If you 
have an autoboot hard-disk system, sub- 
stitute the volume name of your boot 
partition for DFO: in the commands.) Be- 
gin by typing the following in the Shell: 

COPY * TO DF0:Utilities/NLQ2 

ESC[lm 
ESC [4"z 

Press the CTRL and \ keys simulta- 
neously to exit. Once the drive light goes 
out, enter: 

COPY * TO DFO:Utilities/NLQ 
COPY DF0:Utilities/NLQ2 to prt: 



Compiled by Tim Walsh 

Again, press CTRL-\ to exit. Start 
IconEd (found on the Extras disk) and 
load a Project icon, such as one for a 
NotePad file. Save it to your Workbench 
Utilities drawer with the path- and file- 
names of DFO:Utilities/NLQ. Next, open 
the Utilities drawer and highlight the 
NLQ icon. Select Info from the Work- 
bench menu, change the Default Tool to 
c/IconX, and then click on Save at the 
bottom of the Info screen. 

Thereafter, when you want to print in 
NLQ mode, just double click the NLQ 
icon. An IconX window opens briefly, 
and the paper in the printer advances 
two lines. You'll find that the print qual- 
ity is heavy and dark.

Saving Paper 

A PAPER-CONSERVATION measure I 
practice on both my QMS PS810 laser 
printer and Star Micronics LaserPrinter 
8 is to try to use both sides of each sheet 
of paper. Most Amiga word processors 
offer an option to print just the odd- 
numbered pages. After printing the odd 
pages, place them face down in the lop 
paper guide, which can hold almost fifty 
pages, and then print the even-num- 
bered pages.

Tick Tock Tip II 

THE MAY 1990 issue's tip lor setting the 
date on Amigas lacking a date and lime 
clock ('Tick Tock Tip," p. 102) was use- 
ful, but it stops the startup process. In- 
stead, you can start another CLI for the 
clock task and let the boot process con- 
tinue undisturbed. First of all, type the 
following file into a text editor and 



save it in the S: directory as Datesetter: 

DATE 
DATE? 

SETDATE datefile 
ENDCLI 

The Setdate command sets the date of 
the named file, in this case an empty file 
called datefile. To create datefile, enter 
ECHO >datefile in the Shell. Next, early 
in the startup-sequence, add the follow- 
ing line: 

NEWCLI "CON:150/10/300/50Set 
Date" s/datesetter 

Now, when the computer is reset or 
first turned on, a small window appears 
displaying the dale and a request to set 
it. Because the Amigas operating system 
sets the time at boot to the time of the 
newest file on the boot disk, rebooting 
your Amiga several times in one day 
leaves the date correct. All you have to 
do is set the time.

Disk Wipes? 

NEED AN ECONOMICAL, original stor- 
age box for 37.,-inch disks? Try an empty 
84-count diaper wipes box. One of these 
all-purpose boxes can hold 25 megs of 
floppy disks with room to spare. For 
long range storage, put the disks into a 
plastic bag to keep out dust and mois- 
ture and place the bag in the wipe box. 
Their lids snap shut, and they stack 
beautifully.

WHAT'S NEW? 

Get ready for a trip through time, a battle of the sexes, and enough 
stuff to keep your mind off August's heat. 



Compiled by Jan Jackson 



Time and Time Again 



NOW PICTURE THIS: You 

are going about your business 
when, after some exploring 
(curiosity is your forte), you 
uncover a time machine. Per- 
forming its intended task, the 
machine hurtles you back into 
the Middle Ages to uncover an 
intergalactic plot woven by 



aliens. Future Wars: Adven- 
tures In Time (S49.95) chal- 
lenges you to unravel puzzles, 
defeat foes, and rescue cap- 
tives while crisscrossing 
through time. (Interplay: 3710 
S. Susan, Ste. 100, Santa 
Anna, CA 92704, 714/549- 
2411.) RS# 502. 




"When and where am I now?" 



Jamboree 

NOW THAT YOU are too old 
to be a Mousketeer, what can 
you do to fill the void? Disney 
Software's Animation Studio 
can help you create full-length 
animations with characters of 
your own invention. You can 
use the paint and animation 
programs provided to produce 
eel animated clips. The package 



can teach elementary to ad- 
vanced techniques such as 
squash and stretch, arc of mo- 
lion, in-betweening, and path 
of action. Learn how to pro- 
ceed from a rough concept to a 
polished product complete with 
music, sound effects, and 
speech. (Walt Disney Computer 
Software: 500 S. Buena Vista 
St., Burbank, CA 9 152 1,818/ 
560-1000.) RS&504. 



Pithy Polyester 

MEET LARRY'S MATCH in 
Leisure Suit Larry 3: Passion- 
ate Patti in Pursuit of the Pul- 
sating Pectorals ($59.95). Play 
Larry the lascivious divorce 
early on in the game, and then 
switch roles to Patti to examine 
Larry's tactics from the receiv- 



ing end. The game includes a 
trivia test designed to screen 
participants for the higher lev- 
els, an hour of original music, 
and an auto-save feature, 
(Sierra On-Line: PO Box 485, 
Coarsegold, CA 93614, 209/ 
683-4468.) RS#503. 



AND THEN SOME 



IT'S THREE FOR one with Odyssey's 
Super Games Pak ($39.99). The first 
challenge, Deathbots, requires infiltrating 
a research facility to undermine a ma- 
levolently managed company that is 
building a gamma bomb. To succeed, 
you must sabotage the project before 
it's complete. The second game, Jail- 
Break, offers multi-level arcade action, 
including blasting bricks with your can- 
non. You can also design and save up 
to 100 levels of original gameplay. In the 
final arcade game, help ByteMan debug 
a faulty circuit board by gobbling bad 
bits on multiple levels, This game fea- 
tures digitized sound effects, scrolling 
screens, and a simultaneous two-player 
option. 

Space War ($39.99) invites you to 
fight for supremacy. Battle your oppo- 
nents against the cold backdrop of 
space while avoiding solar flares, Black 
Holes, and asteroids. (Odyssey Inc.: PO 
Box 367, N. Eastham. MA 02651, 800/ 
323-9421, 508/240-2317). RS#504. 

In multimedia news. Elan Performer 
2.0 (S149) hit the streets supporting 
more image formats and new control fea- 
tures. Performer 2.0 can link directly with 
other applications, thanks to its ARexx 
capabilities. For upgrading information, 
registered owners can contact Elan De- 
sign; PO Box 31725, San Francisco, CA 
94131. 415/359-7212. RS&505. 

For computing with real feeling, try 
TouchDrlver. The program, which em- 
ulates a two-button mouse, is designed 
for use with MicroTouch Screen, a hi- 



res, analog-capacitive touch screen. H 
promises to run Amiga software by 
touch and features an expanded Pref- 
erences menu. You can use TouchDriver 
to operate multiple serial devices via 
multiplexing touch screen controllers. 
The retail price for screen and driver is 
S895. (MicroTouch Systems: 55 Jonspin 
Rd., Wilmington, MA 01887, 508/694- 
9900). RS#506. 

Any program that accepts keyboard 
input can be synchronized with events 
in the outside world by using VldControl 
($30), a general purpose input mecha- 
nism that synchronizes upon command. 

MasterControl (S50) provides the 
same capabilities, but allows asynchron- 
ous interfacing with up to six discrete 
inputs as opposed to the one input used 
by VidControl. (Integral Systems: PO 
Box 31626, Dayton, OH 45431. 513/237- 
8290). RSW507. 

Soft-Logik Publishing parted the cur- 
tains on PageStream 2.0, the latest ver- 
sion of rts desktop-publishing package, 
Now you can use PageStream to draw 
polygons with Bezier cubic curves and 
to load and save tags separate from a 
document. Version 2.0 allows for spec- 
ifications of font sizes and the beginning 
and ending angles of arcs, and it po- 
sitions and sizes an object. Program up- 
grades are available to registered users 
for $75.

FIREBALL MINI DATA SHEET: 

Our competitors aoverlise "as las! as DMA, wilhout the hassles"- or similar. FOR SUSTAINED TRANSFER RATES IN A MULTITASKING 
ENVIRONMENT ( THE AMIGA [.NOTHING CAN TOUCH DMA -PERIOD! The supertast transfer rates of the Fireball are independant of Ihe number 
of tasks operating (impossible with all non-DMA conlrollers. and that includes mcsi currently on the market) While Fireball is moving data to and from 
the disk at high speeed, the CPU is guaranteed plenty ol lime to get on with running multiple programs. The only "hassle" is the more complicated 
engineering required to implement DMA. We draw on ihe expertise of developers in four countries - with this resource and our commitlmenl lo 
engineering excellence, we believe that we make Ihe besi peripherals in the business. DMA stands lor Direct Memory Access - a special piece 
ol hardware that can generate memory addresses and Iransler data between dillerent parts of the computer. DM A moves data more efficiently than 
Ihe CPU - just like Ihe blitter in the custom chips is more ellioenl at drawing lines DMA can also work while the CPU is executing internal operations. 
Naturally there will be limes thai the DMA channel stops Ihe CPU accessing the bus - however Ihe carelul design in ihe Fireball ensures that there 
s plenty of bandwidth left lor the C PU. Fireball automatically slows down when accessing chip RAM. to prevent any problems with overscan. Fireball 
includes Autoboot ROM's , a leature thai can be easily disabled by a switch on the board. FireBall has three status LED's. to indicate proper lunclioning 
of auloconfigure. board seleci. and DMA access The driver supplied with Fireball includes standard Amiga protocol calls to permit easy interfacing 
of drivers for other SCSI devices. Firebal is compalible with the SYQUEST removable drive. The high performance Fujitsu drives used with Fireball 
nave equivalent access limes to Quantum drives. They also feature embedded sector servo for continued dafa integrity over a wide operating 
temperature range. The optional five year warranty is indicative ol the quality of these drives,

HELP KEY 

Just when you're ready to toss in your Amiga as a boat 
anchor, Lou the Lifeguard springs to its rescue. 



Two Too Many 

Q: My A500 is equipped with a 
512K expansion module (the 
A501) and an 8-megabyte Micro- 
botics 8-UP board, giving me a 
total of nine megs of RAM. I'm 
adding a fiard disk, and I want to 
get the GVP Impact SCSI control- 
ler with an additional two megs of 
RAM. Can I use the AmigaDOS 
1.3 command MERGEMEM 
to access this, giving me a full 
11 megs? 

D. Hoffmann 
Corning. AT 

A: Sorry, but those extra two 
megs would be wasted, at least 
for today. The A500 and 
A2000 both have a 9-meg 
memory limitation (at one 
time no one ever thought they 
would need even that much), 
which can be surpassed only 
by making some severe hard- 
ware and software hacks to 
your system. To be on the safe 
side, I called GVP to make 
sure the developers didn't 
have any surprises up their 
sleeves, and the technical-sup- 
port representative told me 
they do plan on some post-2.0 
hardware that would allow 
you to exceed the limit. We 
will have to wait and see what 
they (or others) come up with. 

On the other hand, A3000 
owners don't have any practi- 
cal limits to the amount of 
memory they can have. The 
motherboard can handle up to 
18 megabytes, and you can 



By Louis R. Wallace 

put much more than that in 
one of the Zorro 1 1 1 slots by 
using a memory board. 



Recyclable RAM? 

Q: / already liave an A 1000, but 
I am thinking of buying one of the 
new A3000 systems. My question 
concerns RAM chips. Will I be 
able to use any of the chips in my 
A 1 000 or its expansion RAM 
boards? Exactly what kind of 
RAM chips does the A3000 use? 
Fred Lonzaloes 
LosAngeles, CA 

A; It's possible, but it depends 
on the type of RAMs used in 
your A1000 expansion device. 
There is information in the 
A3000 documentation on the 
chips it can use. You can use 
either 256K.X4 (giving a total 
of 6 megs) or 1 M x 4 chips (for 
a total of 18 megs), but they 
cannot be mixed together. The 
suggested RAM speed is 80 
nanoseconds or less, and you 
can use either page or static- 
column mode chips. 



Snap, Crackle, 
And Pop 

Q: I'm having a problem display- 
ing interlaced high-resolution 
screens. After working for about 
an hour (ustng programs like 
IntroCAD and Design3D), my 
screen begins to deinterlace. It ap- 
pears that I'm losing every other 
scanline. Eventually, the scanlines 
do reappear. In addition, my 



A 1084 monitor often makes a 
high-pitched whine as well as 
static discharge sounds. Do you 
have any ideas or suggestions ? 

B. Gregor 
Salem, OR 

A: 1 strongly urge you to take 
your system to a service center 
for a checkup. If left alone, it 
might get worse and cause 
other, expensive and avoidable 
hardware failures. I have 
heard of problems with A 1084 
monitors making occasional 
"snapping" and "popping" 
sounds, but the sounds don't 
necessarily mean the monitor 
is failing. Your Amiga is a 
fairly expensive investment, 
and making that trip to the 
service center often pays off in 
the long run. 



Crossing 
Directions 

Q: Help! I have an A2286 AT 
Bridgeboard, and I really like it. I 
would like to get more information 
on using it, but don 't know where 
to look. I've called Commodore 
and can never get anywhere; the 
Amiga magazines hardly ever of- 
fer articles on the subject; and the 
PC magazines never talk about 
them. Where can I find help on 
using my Bridgeboard? 

G. West 
Seattle, WA 

A: A great source of informa- 
tion is Amiga Crossings, a 
monthly newsletter devoted to 



users of Amiga Bridgeboards. 
Published by Marion Deland, 
it costs $40 a year. Direct your 
questions and requests to 
Amiga Crossings, 345 East 93rd 
St., Apt. 26E, New York, NY 
10128. 



Transfer Update 

Casey Perry of Columbus, 
Ohio wrote to Help Key to of- 
fer another, cheaper solution 
for J. Riedel's problem of 
transferring MS-DOS spread- 
sheet files to the Amiga (jun. 
'90, p. 106). Casey recom- 
mends using a program called 
PCPATCH (found on Fred 
Fish Disk #2 18), which makes 
changes to the PCCOPY and 
PCFORMAT programs in your 
1.3 PC UTILS drawer. 
PCPATCH allows these pro- 
grams to work on the .Amiga's 
drives as long as the disks are 
in 3V,.-inch, 360K PC format. 

1 did some checking, and 
the same program is also avail- 
able on PeopleLink in the 
Amiga library. The file refer- 
ence number is 13973. On 
CompuServe, it is in the Amiga- 
Tech libraries under the name 
PCPArC.ARC. On GEnie, look 
for PC_TO^\MIGA.ARC (file 
number 5369). GEnie also has 
an upgrade called PCPATCH2. 
ZOO (file number 6135) that 
will work on 720K MS-DOS 
disks as well as on Atari ST- 
formatted disks. ■

Adieu, adieu 
cher Guru 

By now, you have heard thai Work- 
bench 2.0 transports our beloved guru 
of errata into oblivion. For those who 
might miss this annoying friend, we 
have come up with a list of all-new 
Gurus: 

Guru meditation #900001025: 
Sneeze error. Keyboard too slippery 
for use. Potential viral risk. 

700005567: Big Brother Corrupt. 
This message is provided to inform 
you ol keyboard taps. 

2000666: Breaktime Buddy. The 
Computer has determined that 12 
nonstop hours of computing is too 
much. Go to the bathroom.

Ear to the Wall 

Good for what ale's you. Our Canadian neighbors 
will be seeing a Molson Brewing Company commercial 
smacking of Amiga animation. The first-place winner 
in Amiga World's animation contest, Stephen Menzies, 
recently told us that his prize-winning FeO footage will 
appear in Molson's summer advertising campaign. He 
also said, however, that he was unsure whether those 
of us south of the border would be able to view said 
ad on L'S TV. 

How is your Deutch? Time is running out for those 
of you trying to win that free trip to Amiga '90 in 
Cologne, West Germany in INOVAtronics CanDo con- 
test. The Grand Prize includes two round-trip tickets 
plus hotel accommodations. Pack up your CanDo ap- 
plications and ship them off to INOVAtronics (8499 
Greenville Ave., Ste. 209B, Dallas, TX 75231,214/340- 
4991) before the August '5 1st deadline lor eligibility. 
Three first-prize recipients will receive $500 credit 
towards the purchase of merchandise from participat- 
ing dealers. Five second-prize winners will receive S 100 
credit. Twenty third-prize winners will receive the 20 
best applications submitted. Contact INOVAtronics for 
the contest rules. 

CPU crisis line. By now, most of you have heard of 
Commodore's new 24-hour, toll-free helpline. Al- 
though it sounds very much like a suicide hotline, it 
is not. However, it may reduce anxiety attacks among 
frustrated but otherwise proud new A500 owners. 
Commodore's V. P. of Customer Satisfaction Jim Reeder 
claims the hotline is the first of a number of innovative 



new services in the works. Commodore Express, a 
door-to-door customer service program for A500s, is 
also part of Reeder's plan. The helpline service offers 
assistance in the setting up and operation of new Ami- 
gas. II an ailment is undiagnosed, the unit is picked 
up, replaced or repaired, and returned— all free of 
charge. 

Computer of champions. At press time. Commodore 
was in final negotiations with the 1992 Olympic com- 
mittee. Commodore l.ld.'s Greg Kohler said this is an 
opportunity for the Amiga to play a major role in the 
Barcelona, Spain games. 

Mutiny. Several former Paragon Software program- 
mers are oif on their own with a new company called 
Event Horizon Software. An Event Horizon spokesman 
cited personal and creative differences as reasons for 
the rift. 

Texas Swing. According to a spokesman for Texas- 
based Applied Engineering, we should very soon be 
seeing a high-density floppy drive and modems that 
can be upgraded for sending fax transmissions. 

Adding on. The colorful crew at Comp-U-Save is 
going international, according lo a company repre- 
sentative. A high-profile personality was recently spoi- 
led in Europe looking for leads. 

Holy Smokes! Amiga '90 show attendees saw an in- 
teresting sight in Basel, Switzerland recently — an IVS's 
Trump Card Pro prototype running 3'/ s minutes of 
low-res HAM images at 30 frames per second (with 
sound) off a hard disk. 



69000005: Bus error. Scab key- 
board smashed by a striking Grey- 
hound worker. 

90000399: Code blue guru, A string 
of commands went down the wrong 
way. . .your computer is choking; ad- 
minister the Sassenrath maneuver! 

1 11551 4645B: Flotsom and Jetsam 
Checksum. You and your Amiga are 
sailing the salty seas— and taking on 
water. Check the bilge pump to see 
if it is functional, then signal the Coast 
Guard and back up your hard disk. 

800340500: Goo Error. Cutesy 
chocolate floppy disk lodged in real 
floppy disk drive. Total meltdown. 
Time to punish the little one. 

8009500: Illegal Instruction. Amiga 
unwilling to participate in cock-eyed 
bank-fraud scheme. 

9000056: Insufficient Memory. Over- 
loaded user failed to remember all 
significant commands. System re- 
quests user buy Nintendo. 

400050007: Different plane error. 
You are being contacted by an inhab- 
itant of the netherworld. Shut off alt 
interior lights, reboot, and then await 
further instructions. 

00007892: Recallbrate:checkmate. 
Your multitasking Amiga has been 
playing a game of mental chess with 
Uri Geller. and. . .congratulations, it 
just won! 

7878787878: Exec check failure. Un- 
der special circumstances (full moon. 
Mercury in retrograde, etc.), your sys- 
tem can detect your contact with IBM 
CPUs. Using the CLI. key in an apol- 
ogy and pray your system possesses 
a capacity for forgiveness, 

2205405: Wife Alert. The Computer 
has determined that 24 nonstop hours 
of computing is too much. Pay atten- 
tion to your wile.

p / Totally radical music f 

^ ' software from Dr. T's! / 

ood music software should be as personal as a vintage guitar, and as powerful 
300 watt amplifier stack. Our sequencers have always been able to configure the 
elves to the way you want to work. The V3.0 Level tl and KCS revisions are ev 
lore powerful and easier to use than ever before. 

ur Mufti Program Environment"' allows dynamic data transfer, as well as standi 
lultitasking. Transcribe directly from the sequencer to Copyist, record your Cag 
rtist editor "moves" directly into the sequencer, or use Auto Mix (included ft 
ith V3.0 Level II and KCS) to perform real time "MIDI mixdowns." If you need 
/ric to tape, our Phantom 1 ' SMPTE synchronizer locks you up faster and cheai 
tan you would have dreamed! And Dr.T's has added Laurie Spiegel's acclaim 
lusic Mouse program to our line of quality products. And if you are looking 
great place to start try TIGER Cub, with sequencing and scoring for only $9! 



r.T's, software of quality and po 






t will never go out of style!
